The cost of a restoration depends on how much you do yourself! When real Factory 340, 383 and 440 A Body Cars are done right they get rewarded good money in return. Good deals are out there. But most of those cars sold under value, there is a lot of stuff wrong with them. Most serious Cars are sold private never being advertised, I deal people that do this all the time.
The average A body is a cheap car to buy done.
