cooper question

ive tried checking this out on the mini website but i cant seem to find it. does anyone know if you can get a mini cooper from the factory without any back seats. just a flat carpeted bed like the back of an suv. i want to do a very large stereo install and i need the extra room in the back. i had considered just taking the back seat out but that leaves the floor very irregular and not nearly as clean looking. thanks for any help
