or what you could do is buy my car for $6000, '97 Honda Prelude. I already have it started for you with a few mods...

if not, its really gonna be your own personal discretion. I mean i can say the Prelude is the best car, but it might not be for you. Also how much are you thinking about spending total? Either you could get a really really cheap car and build it, or a better car for a little more and build it a little less.
