About the BMW 3 Series Touring 2023 boot

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.

About the BILLY Bookcase, oak effect, 31 1/2x11x79 1/2 " package

The BILLY bookcase ships as one long, flat, heavy box: 81¼″ × 11¾″ × 5″ and 87 lb 5 oz. The length is the challenge, not the bulk. That long panel needs floor space most boots only find with the rear seats down. The flat-pack board is rigid, so it will not bend around a wheel arch or curl into a short boot. An estate, a hatchback with the seats folded, or an SUV handles it best. Slide it in long-edge first, low and flat, and protect the corners, because at this weight a dropped end can split the board.
