Will KARMSUND Floor mirror, black, 15 3/4x65 3/4 " fit in a VW Tiguan 2024?

The Tiguan gives you a wide, fold-friendly boot. The opening is 42⅞″ across and 29⅛″ tall, one of the wider tailgate openings in this class. Seats up, the floor runs 34⅝″ deep, enough for cases and boxes but not long panels. Fold the rear bench and it opens to 67¾″, a gain of 33⅛″, so the boot doubles as a load bay for flat-pack. The narrowest floor width is 39¾″, and there is only a ⅜″ drop from the sill to the floor, so loading stays flat. Tall items suit it better than very long ones unless you fold.

One long, thin box: the KARMSUND mirror ships as a single package at 65″ × 16¼″ × 1¼″ and 21 lb. The weight is nothing; the shape is the whole job. A 65″ carton with glass inside cannot bend around a seat gap or ride upright, it wants one flat, straight run, and few cars offer that with the rear seats up. Fold the seats in a wagon, hatchback or SUV and the length usually clears. Feed a top corner through the opening first, lay the box flat on a blanket with the glass side up, and stack nothing on top. The corners are the weak point, so pad both ends before it leaves the store.
