WillBISSA Shoe cabinet with 3 compartments, white, 19 1/4x11x53 1/8 "fit in aBMW 3 Series Touring 2023?

The BMW 3 Series Touring gives you a wide estate tailgate, 39 3/8 inches across and 28 3/8 inches tall, with a low loading sill at 23 5/8 inches and almost no drop to the floor (about 3/8 inch), so you slide loads in rather than lift them. With the rear seats up the floor is short at 39 3/8 inches, and it narrows to 37 3/8 inches at the back. Fold the bench and it stretches to 68 7/8 inches, a gain of 29 1/2 inches. It handles long flat boxes well only once folded. Keep the parcel shelf out when the load is tall.

BISSA ships as a single flat box, 54¼″ × 16¾″ × 3″, and it weighs 45 lb 15 oz. At 3″ thick it slides into gaps a built cabinet never would, so the thickness is not your problem. The length is. At 54¼″ you need a trunk that measures long enough on the floor, or one rear seat folded so the box can run forward between the seats. Most hatchbacks take it with the seats down, and any wagon or SUV swallows it flat. Lift it on edge with two hands, and rest it on a long edge rather than a corner, because 45 lb 15 oz of flat pack lands hard and the corners split first.
