Practically Speaking, What is This Car Really Worth?

It would have to be pert near perfect, and a high performance model with all of the goodies to even come close to $20k. I have a friend that has a magazine 66 Cuda formula S 4 speed car. He paid $19.5, but it’s perfect in every way, and has been in a lot of magazines. That’s the highest price I’ve seen an early bought or sold for!
