If you sure the metal is that clean and it's not been hacked on that completely changes the value IMO..... You literally can't put a price on a clean original body....
If I owned this car with no rust or filler it would take 10k to change ownership. A good body is worth that much to me and this is coming from someone who absolutely detest the current pricing of the cars in the market. But a clean body is a game changer in a restoration!
