I tell everyone to buy a done car , keep in mind the only thing you need to like is the paint , the rest of the parts can be unbolted and changed . Also keep in mind the body and paint , although expensive is the cheaper part of your build , interiors are running 5 to 8 grand now , good eng and trans are easily 10 grand , front suspension 2 grand , it adds up quick , a nice done cars can be had for usually a third of the cost to build one . Now if the car you wonna build has a some attachment in your life then theres no other choice then build it . Right now there are alot of really nice done cars available and a good deal can be had .
