Jeff,
Like the guys said ... Welcome! If you want to know about Cobras, you came to the right place and an EV Cobra sounds very interesting
For a car to build ... take a look here in Club Cobra classifieds ... or If you are looking for a Factory Five Racing kit, try ffcobra
http://www.ffcobra.com/
and under the Forums tab, take a look in the Classifieds, might be something there that is close to what you are looking for.
Best of luck with the build!
