Again boils done to a value based on "cost to build" ...Personally I think it's over priced by about $10K....but he may have spent lots on it. The rear seat is not "legendary products" nor is it original. The motor looks terrible with rust all over it, doesn't look "fresh" I quick paint job may be on top of original panels, but how much bondo is in between ?
If I was going to invest that kind of money I would want a more invest-able car like a numbers matching 1973 340 car...
