Will a box (84x58x64 cm) fit in a vehicle?

A vehicle cargo area is a 3D box — length, width, and height all matter, and most items can only be loaded in 2–3 of the 6 permutations because of door geometry and load height.

1. Look up the cargo-bay rectangle for the chosen make / model / generation / fit-location (seats folded or removed per the configuration).
2. Generate the orientation permutations the vehicle physically accepts (e.g., low liftgate blocks vertical loading of a tall sofa).
3. For each accepted permutation, apply the constraint: item ≤ cargo on all three axes simultaneously.
4. Pick the permutation with the largest minimum-axis margin — wheel-well intrusion is NOT modeled (see Assumptions).
5. Same ladder as door (verdict-tiers.js): FITS ≥ 2 in; FITS_TIGHT 0.5–2 in; FITS_VERY_TIGHT 0–0.5 in; DOESN'T_FIT below.

Cargo-bay dimensions come from the manufacturer’s published spec, not from a physical measurement of your specific vehicle.
