i had a coupe you knuckleheads. you can fit 10 cubes. i had a 13 cube external wall in mine back in the day. built completely outside of hte car. pull your seats and console and slide it in. do not screw to the floor in the backseat area. the gas tank is under the seat. how good are your building skills. you can get like 8 cubes in the trunk if you glass the tire well and all that.
