A very good example of resto cost and value of a 69 Cuda

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.

i agree.

And another factor is the ability and willingness to hunt and research good values on parts and outside services.

If you want everything right now and don’t like shopping for your used and new parts, you’ll probably spend much more than another person that will.

also, many of us have seen people overpay for poor quality outside work (paint, body, upholstery, chrome, etc). Not uncommon to see one person pay $25K for paint and body that is the same quality as another person pays $15K for.

The differences in parts and labor spent can add up to huge amounts.
