Add up what it will cost you for the car, the parts, the interior, all the rechrome costs, engine and tranny rebuilding costs, shipping costs and materials to do it correct, then any labor you will have to pay out and count your time as worth nothing then you will have an idea of what it will really cost. Then reality sets in when you figure out how many things you forgot to add in in the begining and all the surprises that popped up. Don't worry about the cost if you have money to spend and it won't put you in a finanical bind later, just do it for the love of the hobby if you can afford it in the long run.
