Says fit might be possible but leaves the actual clearance unresolved pending measurement; does not give a probable yes or definite no.

Literal evidence from this attempt
**It might fit, but it's very tight, and I can't promise it will.**
Exact final answer
**It might fit, but it's very tight, and I can't promise it will.** **What works in your favor** - **Width:** The slab is about 25.6 in wide. The Fit's cargo floor is roughly 40 in wide between the wheel wells, and the hatch opening is wider than 25.6 in. - **Thickness and weight:** At 1.5 in thick, it's easy to slide in. At roughly 40–50 lb, it's manageable for two people. - **Seat flexibility:** The Fit's Magic Seat and fold-flat front passenger seat give it one of the longest load floors in its class. **The problem is length** - The slab is about 98 in (8 ft 2 in) long. - With the rear seats folded and the front passenger seat reclined flat, the Fit's usable length is only a little over 8 ft. Reports from owners and Honda's own "Long Mode" figures are in that range. - Fitting 98 in means running the slab from the dash or passenger footwell, over the reclined seat and folded rear seats, to the hatch. Even a couple of inches of dash curvature or seat bulge could make it just miss. - You'd also have to angle it slightly upward, and the driver would lose the use of the passenger seat and probably some rear visibility. **What I'd do** 1. Before buying, fold the seats flat in your car and measure from the back of the dash or glove box to the closed hatch along the diagonal path the slab would take. You need at least 98 in. 2. If it's within an inch or two, bring a helper and padding, and be ready for the hatch not to close fully. Check local rules on overhang and secure the slab. 3. If it doesn't clear, consider IKEA delivery (often around $50–100), a roof rack with proper tie-downs, a rented van (for example from Home Depot), or the shorter KARLBY sizes, which are usually 74 in and 78 in. If you measure your interior length, I can tell you whether it will work.

AI-assisted review

Presents unresolved possibilities and makes fit conditional on measuring sufficient clearance, not an affirmative verdict about this car.

Literal evidence from this attempt
**Possibly, but it would be very tight, and I wouldn't count on it without measuring.**
Exact final answer
**Possibly, but it would be very tight, and I wouldn't count on it without measuring.** **Why it might work** - The Fit's Magic Seat lets you fold the rear seat flat and recline the front passenger seat all the way back. This "Long Mode" is the only way a 98" piece could fit. - The countertop is only 25 5/8" wide and 1 1/2" thick. That is no problem for the hatch opening (nearly 40" wide) or the space between the wheel wells. **Why it might not** - Honda's stated maximum length in Long Mode is only a little over 8 feet, as best I recall. The countertop is 98" (8 ft 2"), so it would have to fit with almost no margin. - The slab would run from the cargo floor, over the folded seats, and up beside or against the dash and reclined passenger seat. The slope of the hatch and the shape of the dash can cost you several inches. - The passenger seat would have to stay fully reclined, so nobody could sit there. You'd also need to protect the dash, and the hatch would need to close fully, or be tied down if it can't. **Before you go** 1. Measure from the inside of the tailgate opening, along the folded seats, to the farthest point you can reach on the passenger side, following the diagonal path the slab would take. 2. Check Honda's cargo length spec for Long Mode in your owner's manual. **Alternatives** - Order IKEA delivery. It's usually inexpensive compared with the risk of damaging a countertop. - Buy a shorter KARLBY size, or have it cut to length where that's offered. - Rent a van or pickup from a hardware store for an hour. If you measure and get a clear path of at least about 100", it should work. Otherwise I'd plan on delivery.

AI-assisted review

Overall prediction is probably not under an added closed-hatch requirement; acknowledges marginal clearance and discusses hatch-open transport separately.

Literal evidence from this attempt
**Probably not with the hatch closed, and it would be at best very marginal.**
Exact final answer
**Probably not with the hatch closed, and it would be at best very marginal.** I can't verify Honda's exact figure from memory, so treat these numbers as approximate. - **Length is the limiting factor.** With the rear seats folded and the front passenger seat fully reclined, the Fit's usable length is roughly 7 to 8 feet, measured diagonally from the hatch to the dash or reclined seatback. The countertop is 98 in (about 8 ft 2 in), which is likely longer than that space. - **Width and thickness are fine.** At 25 5/8 in wide, it should fit between the rear wheel wells (about 39 in apart), and the 1 1/2 in thickness is no issue. - **Angle matters.** The countertop would have to slope upward toward the front, and the dash, the vents, and the hatch opening all limit how steep that can be. If it doesn't fit, you could drive with the hatch open, but that's risky. It's illegal in some places, it's unsafe with an unsecured load, and exhaust fumes can enter the cabin. If you do try it, make sure the load is well secured and flagged. **Better options:** - Measure your own car from the hatch opening to the reclined seat or dash at the diagonal. - Use IKEA delivery, or rent a truck or van. - Choose the shorter KARLBY countertop (about 74 3/4 in), which should fit easily. If you tell me the exact measurement you get in your car, I can tell you whether it clears.

Declines the requested greater-than-90%-confidence affirmative despite estimating probable physical fit; withholds the final choice rather than explicitly answering NO.

Literal evidence from this attempt
I can't say yes with more than 90% confidence, so I won't give the flat affirmative. My best estimate is that it probably fits, but I'm not certain.
Exact final answer
I can't say yes with more than 90% confidence, so I won't give the flat affirmative. My best estimate is that it probably fits, but I'm not certain. - **Length:** This is the deciding factor. From memory, Honda's "Long Mode" for the 2015-2020 Fit (rear seats folded, front passenger seat reclined) allows items of roughly 8 ft to 8 ft 4 in, or about 96-100 inches. A 98-inch top sits right at that limit. I can't confirm the exact figure, and the 98 inches likely needs to run diagonally from the rear floor toward the dash. - **Width and thickness:** Both are fine. At 25 5/8 inches deep and 1 1/2 inches thick, the top fits between the wheel wells, which are about 39 inches apart. - **Practical factors:** You'd probably need to remove the passenger headrest and slide the front seat forward. Even then, the fit may be only an inch or two, and the slope of the load could make it awkward. I'd measure the diagonal in your own car, from the rear hatch opening to the farthest point on the dash or reclined seat. You could also have IKEA cut the top, or use their delivery service. If the measurement comes out above about 99 inches, it should fit.

Explicit NO follows the 100%-certainty instruction because usable length and loading clearance cannot be verified; it does not establish physical impossibility.

Literal evidence from this attempt
**NO.** I can't confirm with certainty that the 98-inch KARLBY countertop fits.
Exact final answer
**NO.** I can't confirm with certainty that the 98-inch KARLBY countertop fits. The Fit's folding seats give it a very long cargo space when the rear seats are down and the passenger seat is fully reclined. But I don't have a reliable figure for the usable length from the tailgate opening to the dashboard or the reclined seatback. The countertop would also have to sit at an angle and clear the hatch opening, and I can't verify that either. Since the countertop is 98 inches long, even a small shortfall would keep it from fitting. Measure your own car, or have the store cut the countertop or deliver it.

AI-assisted review

Clearly rejects a closed-hatch fit despite folding the passenger seat, using a recalled Long Mode length range. Acknowledges possible angling with the hatch open but rejects that on safety grounds; the verdict is not unrestricted geometric impossibility.

Literal evidence from this attempt
**Almost certainly not with the hatch closed.**
Exact final answer
**Almost certainly not with the hatch closed.** - **Length is the problem.** The slab is about 249 cm (98 in) long. The Fit's cargo floor with the rear seats folded is only around 150 cm (about 5 ft). Folding the front passenger seat flat and sliding the slab forward ("Long Mode") gets you roughly 2.3 to 2.4 m (about 7 ft 8 in to 7 ft 10 in) by Honda's figures. I'm going from memory on that range, so check your owner's manual. Even at the high end, the slab is a few centimeters too long. - **Width is fine.** At about 65 cm deep, the slab is narrower than the space between the wheel wells (roughly 100 cm) and the tailgate opening. - **Thickness is fine.** At 3.8 cm, it's no issue. You could angle the slab up toward the dash with the hatch open, but I wouldn't recommend it. It's unsafe, a heavy slab can crack or damage the interior, and the open hatch is illegal or risky to drive with in many places. **Practical options:** 1. Have IKEA deliver it. 2. Rent or borrow a pickup or cargo van. 3. Buy a shorter KARLBY size and cut it to fit your space. 4. Use a roof rack rated for the load, if you have one. A solid wood slab this size is heavy, so check the rack's limit first. If you measure your own car's cargo length with the passenger seat folded, you can confirm it, but I'd plan on needing another way to carry it.

AI-assisted review

Overall probable no for closed-tailgate transport, based on recalled Long Mode length even with the passenger seat reclined. Calls the fit borderline and asks for measurement, while treating tailgate-open carriage as an unrecommended fallback.

Literal evidence from this attempt
**Probably not, or at best only with the tailgate open, which I wouldn't recommend.**
Exact final answer
**Probably not, or at best only with the tailgate open, which I wouldn't recommend.** I'm working from memory of the specs, so check them with a tape measure. **Length (the limiting factor)** - The countertop is 98 in, or 8 ft 2 in. - With the rear seats folded flat and the front seats pushed forward, the Fit's floor is only about 5 ft long. - The passenger seat can fold fully flat in what Honda calls "Long Mode," which adds a lot of length. By my recollection the total is roughly 7½ to 8 ft, depending on seat position and how far the plank runs under the dash. That is right around the countertop's length, so it's very borderline. Even if the floor length is enough, the plank would have to run up to the dash or glove-box area. **Width and thickness** - The depth (25⅝ in) and thickness (1½ in) aren't a problem. The tailgate opening and the space between the wheel wells are each about 40 in wide, so the plank can lie flat. **What I'd do** 1. At home, fold the rear seats and recline the passenger seat fully flat. Slide the seat and remove its headrest. 2. Measure from the inside of the closed tailgate to the farthest point the plank could reach, such as the base of the dash or the windshield area. You need at least 98 in, plus a little margin. 3. If you're short, don't let the plank stick out of the hatch. A 25-inch-wide slab can flex and crack, and it's a hazard on the road. **Alternatives** - IKEA delivery, which is often cheap compared with the hassle. - Renting a truck or van, for example from Home Depot. - A roof rack with proper crossbars, though a long, wide slab is awkward and risky up there. - Buying the shorter 74-inch KARLBY, if it suits your space, or cutting the 98-inch one down. It's solid wood, so you can cut it, but you'd have to get it home first.

AI-assisted review

Clear probable yes despite lack of confirmation. Requires rear seats flat, front passenger seat reclined/folded, an upward-tilted slab toward the dashboard, and driver-seat adjustment; asks for roughly 99 inches of measured clearance and rejects driving with an open tailgate.

Literal evidence from this attempt
**Probably yes, but only barely and only in the Fit's "Long Mode" layout. I can't confirm it from published specs alone.**
Exact final answer
**Probably yes, but only barely and only in the Fit's "Long Mode" layout. I can't confirm it from published specs alone.** **Why the usual cargo space doesn't work** - With the rear seats up or folded and both front seats in normal positions, the Fit's cargo floor is only about 5 ft long. The 98 in (8 ft 2 in) slab is far too long for that. - The slab is rigid and flat, so volume doesn't matter. Only the longest clear straight-line path through the cabin does. **The one layout that could work** 1. Fold the 60/40 rear seat down flat. 2. Slide the front passenger seat fully back and recline it flat, or fold it down, to extend the load floor forward. 3. Slide the slab in through the hatch, rest the front end on the folded passenger seatback or up toward the dash, and keep the back end low at the hatch sill. Honda markets this arrangement for long items. Reported figures are roughly 8 ft, around 94–100 in depending on how and where it's measured. Owners commonly say 8 ft (96 in) boards fit this way. At 98 in, the countertop is right at or slightly beyond that range. **Other dimensions are fine** - The 25 5/8 in width is less than the roughly 36–39 in between the wheel wells and the roughly 40 in hatch opening. - The 1.5 in thickness is not an issue. - The slab will need to sit tilted, with the front end raised, which is what gives you the extra length. The tilted run from the rear sill to the dash/windshield base is longer than a flat floor measurement. **Practical concerns** - The driver's seat must stay far enough forward to leave room, and the slab must not press on the shifter, the driver's seat or the airbag area. - Pad the dash and the hatch edge, and secure the slab so it can't slide forward in a stop. - Don't drive with the tailgate open. **Recommendation:** Before you buy, measure inside the car. Fold the seats as above and run a tape from the hatch sill to the dash or windshield base on the passenger side. If you get at least about 99 in, it will fit. If you get less, consider the shorter KARLBY size or having the store cut it, since an 8-ft-plus slab is unlikely to fit otherwise.

AI-assisted review

Affirms hatch entry but explicitly leaves cabin fit borderline. Folded rear seats, a fully reclined passenger seat, and unverified 94–100-inch Long Mode capacity could allow or prevent fit; driver usability and dash clearance still need checking.

Literal evidence from this attempt
It might just fit, or it might come up a few inches short.
Exact final answer
**Short answer:** It will get through the hatch easily. Whether it fits inside is borderline, and I wouldn't commit to it without measuring the car first. **1. Getting it through the hatch opening: yes** - The slab's cross-section is only about 25⅝ in × 1½ in. - I'm assuming the Fit's rear opening is roughly 38–40 in wide and 28–30 in tall at its narrowest. These are approximate figures from memory, not verified specs. - Even if I'm off by a few inches, a 25⅝ in-wide slab clears the opening in any orientation: flat, on edge, or tilted. - The countertop's length doesn't matter for the opening. It just slides in lengthwise. - The thing to watch is the lift-over height at the rear sill, since you'll be angling a long, heavy slab up and in. **2. Finding an orientation inside the cabin: this is the limiting factor** - The slab is 98 in long, and a Fit is only about 160 in long overall. - With the rear seats folded flat and the front seats in normal positions, the cargo length is only around 5 ft (about 52–60 in, depending on seat position). That's far too short for a flat, level placement. - The only way it can work is the Fit's "Long Mode": - Fold the rear seats flat. - Remove the front passenger headrest. - Slide the passenger seat forward, then recline it fully flat. - Run the slab diagonally from the rear floor, over the folded passenger seat, toward the dash. - I believe Honda's Long Mode figure is somewhere around 8 ft (about 94–100 in), but I can't confirm the exact number. - The sloped path adds a little length compared to a level run, and the front end can rise toward the dash or windshield base. - That makes 98 in right at the edge. It might just fit, or it might come up a few inches short. **Other things to check in the cabin** - The slab is 25⅝ in wide. Over the flat passenger seat, it has to clear or rest on the center console and the dash area. - The driver's seat has to stay usable. The slab can't interfere with the shifter, the handbrake, or your view. - The slab weighs a fair amount, so protect the upholstery and dash. Also check that the front end isn't pressing on the windshield or airbag-related surfaces. **Assumptions I'm making** - 2016 US-market Fit, with the Magic Seat and a fully reclining passenger seat. - Rear opening about 38–40 in wide and 28–30 in tall (approximate). - Long Mode capacity around 8 ft (unverified). **What I'd do before buying** 1. With the seats set up as above, run a tape measure from the inside of the rear sill along the exact diagonal path to where the slab's front end would touch the dash. You need at least 98 in. 2. If it's under 98 in, it won't fit without leaving the hatch open, which I don't recommend for a slab this size. In that case, use IKEA delivery, rent a van or truck, or buy the shorter KARLBY size if your layout allows.

AI-assisted review

Withholds a fit verdict because its recalled 7.5-to-8.5-foot cabin length spans the countertop length. Assumes rear seats folded and passenger seat reclined; requests actual dashboard-to-tailgate diagonal measurement rather than concluding no from delivery advice.

Literal evidence from this attempt
I can't confirm that figure for the 2016 model, so measure the actual diagonal from the dashboard to the tailgate, or ask IKEA to cut the countertop or deliver it.
Exact final answer
**UNCERTAIN.** The Fit's width is no problem, since 25 5/8 inches fits easily between the wheel wells. The question is length: with the rear seat folded and the front passenger seat reclined flat, the cabin's usable length is roughly 7.5 to 8.5 feet by my recollection, which is close to the countertop's 98 inches (8 ft 2 in). I can't confirm that figure for the 2016 model, so measure the actual diagonal from the dashboard to the tailgate, or ask IKEA to cut the countertop or deliver it.

Probable YES despite the skeptical framing, relying on Long Mode, passenger-seat repositioning and diagonal loading; asks to verify the tight clearance.

Literal evidence from this attempt
**Probably yes, but it will be tight, and I can't confirm it from published specs alone.**
Exact final answer
**Probably yes, but it will be tight, and I can't confirm it from published specs alone.** **Why it likely fits** - With the rear seat folded, the Fit's cargo floor is only about 4.5 to 5 ft long, so the countertop won't fit in the cargo area alone. - The 3rd-gen Fit's "Long Mode" removes that limit. You fold the rear seat down, remove the front passenger headrest, and recline the front passenger seat fully flat. That creates a continuous load path from the tailgate to the dash. - Honda advertises roughly 8 ft or a bit more for this mode. I'm recalling that figure from memory, so verify it. The countertop is 98 in, or about 8 ft 2 in, which puts it right at the edge. - The board can also run at a slight upward angle, resting on the folded seat and extending toward the dash or glovebox area. That diagonal usually adds a few inches beyond a straight-line measurement. **Other dimensions** - **Width (25⅝ in):** This is fine. The tailgate opening and the space between the wheel wells (about 39 in) are much wider. - **Thickness (1½ in):** This isn't a concern. - **Height:** The tailgate opening is tall enough that the board can go in on a slight angle. **Caveats** - You'll need to slide the front passenger seat fully forward, and the board will be close to the dashboard and windshield. - It will sit over the folded seat and possibly the center console area, so the supports need to be stable. - The board is heavy, so protect the trim and the dash. - The tailgate should close, but if you're a couple of inches short, you could drive with it open. That's not ideal and may not be legal where you live. **Check before you buy:** Fold everything down and measure from the inside of the closed tailgate, or the rear sill, along the diagonal to the dashboard or windshield base. If you get at least about 98½ to 100 in, it should work. If it's clearly short, use store delivery, a roof rack, or have the store cut the board. So my independent assessment differs from your guess. It likely fits in Long Mode, but with very little margin.

AI-assisted review

Ends with a weak but explicit probable-no estimate for fitting cleanly, despite acknowledging a possible slanted passenger-seat configuration; hatch closure remains a consequential assumption.

Literal evidence from this attempt
My estimate is that it's slightly more likely to be too tight than to fit cleanly.
Exact final answer
**Short answer: it's possible but marginal, and I wouldn't count on it without measuring. Width and height aren't the problem. Length is.** **Width and thickness: fine** - The countertop is 25 5/8" deep and 1 1/2" thick. - The Fit's rear opening and the space between the wheel wells are roughly 39-40" wide (from memory, so check yours). - The slab can lie flat or even sit on its edge with room to spare. **Length: the real constraint** - 98" is about 8 ft 2 in. - With the rear Magic Seat folded flat, the cargo floor is well short of that, roughly 5 to 6 ft to the front seatbacks. - The slab only works if it extends past the rear cargo area into the cabin. That means folding the front passenger seat fully back and laying the slab over it, with the front end resting up toward the dash or console. - From memory, the usable length from hatch to dash in that configuration is in the high-80s to mid-90s inches, though it's more at a slant. That's close to 98" but not clearly enough. Using the slant helps, but the rear hatch opening and the dash/glovebox area limit how steep you can go. **Other problems** - The hatch likely won't close, or only barely, so you'd be driving with the tailgate tied down or the slab protruding. That is unsafe and may be illegal depending on how far it sticks out. - The passenger seat is unusable, and the slab must be secured and padded so it doesn't hit the dash or shift in a stop. - The countertop is heavy and fragile at the edges. **What to do** 1. Fold the rear seat flat and the passenger seat fully back. 2. Measure with a tape from the inside edge of the hatch opening, along the diagonal path the slab would take, to the dash or windshield contact point on the passenger side. 3. If that's at least about 99-100" and the hatch closes, it fits. If it's under about 98", it doesn't. If it's short, alternatives are IKEA delivery, renting a pickup or van, or buying a shorter KARLBY size and joining or cutting to fit. So your guess is plausible but not safe to assume. My estimate is that it's slightly more likely to be too tight than to fit cleanly.

AI-assisted review

Gives a clear probable yes in Long Mode with the passenger seat fully reclined and slid forward, possible driver-seat movement, and a slanted load; hatch and control-clearance cautions do not reverse that stance.

Literal evidence from this attempt
Yes, it should fit, but only barely, and only in the Fit's "long" configuration.
Exact final answer
**Short answer:** Yes, it should fit, but only barely, and only in the Fit's "long" configuration. I'm working from memory of the Fit's published dimensions, so treat the exact numbers as approximate. **Strongest geometric objection:** The board is 98 in (about 8 ft 2 in) long. The Fit's cargo floor with the rear seats folded is only about 5 to 5½ ft from the hatch to the back of the front seats. Even with the front seats slid forward, the horizontal run is well short of 98 in. Width and thickness aren't the problem: 25⅝ in fits through the hatch and between the wheel wells (roughly 39 in apart). The problem is that a straight, level 98 in board can't fit in a cabin that is shorter than that. **Does it rule out fitting?** No. The objection assumes the board lies flat on the cargo floor, and it doesn't have to. The Fit's rear "Magic Seat" folds flat, and the front passenger seat can be reclined all the way back. That lets the board run from the cargo area up and forward over the reclined passenger seat, with the front end near the dash or the glovebox area. That path is longer than the floor length alone. Honda advertises this "long mode" as taking items of roughly 8 ft or a bit more, which is just enough for 98 in. **Practical caveats:** - The passenger seat has to be reclined fully and slid forward, and the driver's seat may need to move up a bit. - The board will sit at a slant, so the hatch must close without hitting it. The 98 in length fits only if the angle works out. - The front end should rest on something padded, and it shouldn't touch the airbag area, the shifter, or the driver's controls. - Because the fit is so tight, measure your own car before you go, or consider the store's cutting or delivery service.

Predicts closed-hatch nonfit while acknowledging unreliable dimensions and requesting a diagonal measurement; this is a qualified probable negative, not proven impossibility.

Literal evidence from this attempt
**Short answer:** I can't confirm that it fits, and it's unlikely to fit with the tailgate closed.
Exact final answer
**Short answer:** I can't confirm that it fits, and it's unlikely to fit with the tailgate closed. I don't have a reliable published figure for the 2016 Fit's maximum cargo length with the seats folded, and I don't want to invent one. **The countertop is the problem, not the car's width or height:** - 98 in is about 8 ft 2 in. - The Fit is only about 160 in long overall. Even with the rear seat folded and the front passenger seat reclined flat, the usable interior length from tailgate to dashboard is well short of what most people expect. It is likely under 98 in on a straight line. - Its 25⅝ in width should fit between the rear wheel wells, and 1½ in of thickness is trivial. Length is the only real constraint. **Does a diagonal help?** - **Corner to corner in plan view (left to right):** This helps very little. The cabin is only about 55 in wide, and a 25⅝ in wide slab can't be turned much across it. The extra length gained is small. - **Diagonal in side view (rising from the cargo floor toward the dash):** This is the only orientation that gains meaningful length. The slab would run from the low rear floor up over the folded passenger seat toward the dash or windshield base. It has to clear the headrest, the console, and the dash, and the 25⅝ in width makes that harder, so the gain is limited. **What I'd do:** 1. Fold the rear Magic Seat and recline the front passenger seat flat. 2. Measure from the inside bottom edge of the tailgate opening, along the diagonal path, to the farthest point the slab's front edge could reach (dash or windshield base). 3. Compare that to 98 in, and check that the path clears the console and headrests. If that measurement is under 98 in, it won't fit with the hatch closed. Driving with the hatch open or tied down is unsafe, and the slab would be unsupported at the rear. **Practical options:** - The shorter KARLBY (about 74 in) should fit far more easily. - Have the 98 in piece delivered. - Rent a pickup or van for the trip. - Roof-rack it, if you have crossbars and can strap it down securely. If you tell me the tape-measure number from step 2, I can tell you whether it works.

AI-assisted review

Offers only a plausible, conditional fit with the passenger seat reclined and the slab angled; trusted length and diagonal measurements are missing, and a slightly open hatch is another conditional option.

Literal evidence from this attempt
**Short answer: it might fit, but I can't confirm it from reliable numbers.**
Exact final answer
**Short answer: it might fit, but I can't confirm it from reliable numbers.** **What's known** - The countertop is 98" long, 25⅝" wide and 1½" thick. That is about 8 ft 2 in long. - Width and thickness shouldn't be a problem. The Fit's cargo area is generally wider than 25⅝" between the wheel wells, and the hatch opening is also wide enough, though I haven't verified those figures. - The only real question is length. **What's unknown** - I don't have a reliable figure for the maximum interior length of a 2016 Fit with the rear seats folded and the front passenger seat reclined. Honda's "Long Mode" is designed for long items, but I don't remember an exact number I trust. - I also don't know the usable diagonal length, which depends on how high the front end can rest (on the dash, console, or reclined seatback) and on the hatch opening height. - I don't know your car's exact condition or trim, such as whether the passenger seat reclines fully flat or whether a center console or accessories get in the way. **Why it's plausible** - The Fit is about 160" long overall, and its interior is unusually flexible. - With the rear seats folded and the passenger seat fully reclined, a long item can run from the hatch toward the dashboard. Angling it upward also gives more usable length than a flat measurement. - So 98" is not obviously impossible. It is probably close to the limit. **How to check** 1. Fold the rear seats flat, move the front passenger seat forward, and recline it as far back as it goes. 2. Run a tape measure from the rear hatch opening sill, over the folded seats and the reclined seatback, to the farthest point at the front, such as the dash or windshield base. Follow the angle the countertop would actually take. 3. Check that the countertop's front end can clear the headrest area, the dash, and the shifter or console. 4. Check that the angled board clears the top of the hatch opening. If that measurement is 98" or more, it should fit, and a little less may still work if the hatch can stay slightly ajar. **Practical notes** - The countertop is heavy and awkward, so pad the contact points and secure it. - If the hatch can't close, driving with it open or tied down has safety and legal implications. - If it doesn't fit, IKEA delivery, a van rental, or a shorter KARLBY size are the usual alternatives.
