About 2720 total into it, it has a fairly nice paint job and nice (red) interior which I'll change later. Pony's look good on it!. If I ever get off my butt and get whatever else I need (fuel mgmt) and time to assemble it should do the trick. Just be patient and shop around the websites and swap meets and it's good to be friends with guys who race at the track or be willing to swap out labor with them.
