Wow, this is very cool to know. Maybe I should get my hands on some EV1 blueprints. I suspect a Saturn SC1 coupe would be the best platform. Also, I remember that the Chevy Geo Storm looked a lot like the SC1 :

Geo Storm

The Geo Storm was a sport compact car manufactured by Isuzu and sold in the United States by General Motors from 1990 through 1993 as part of GM's Geo line of inexpensive automobiles. The same vehicles, with minor variations, were sold in Canada in the 1992 & 1993 model years only. The Storm was intended to be a budget car with the look and feel of a sports car. It replaced the related Geo Spectrum, which was sold in hatchback and sedan, and like its predecessor, it is only sold in 2-door hatchback and station wagon.
