The car is a business coupe. It never had a back seat. Behind the driver bench seat is a storage area that is separate from the trunk. The storage area is the width of the car, 11" deep, and about 15" high. It is accessible from behind the folded forward seat by 2 top locking, bottom hinged doors. The driver side contains my tool box, a jack, and other supplies one might need on the road. The passenger side is reserved for the Mrs to put the stuff she thinks she needs to hide.
