As many guys as are selling cars right now, you would probably be money ahead getting a decent deal on something closer to "finished", whatever you decide you want, be it race car or street car, or whatever. Ant then putting your personal touches on it.

Car sounds like it needs a lot, no matter what route you go, and the $ you sell it for almost never covers what you had to put into it.

But I don't want to be a wet blanket--if you're set on then go for it.
