$40,000 total? Or $40,000 in addtion to the vehicle?

$40,000 total... I would say 89 Mustang Coupe. $3,000 (for the car) and $37,000 in motor and transmission mods. I could go into detail, but you get my point.

That will probably get you the closest to it. But don't count on it being able to go through any turns.
