Seems like the flat front end of this one would really cause a lot of aero drag, and slow the car down.....
A Micro Mini. In England a number of people like to section the Mini and drastically shorten the wheel base. You drive it from what once was the back seat. They tend to be real roadsters - no doors and no top. A friend imported one for his collection.
Chop half the car off then tow around a trailer to carry the stuff that would have fit in the back if it was still there? Weird.
