FWIW- I talked to this guy. He "seemed" on the up. He has no problem with anyone serious having JerrM come and inspect it. And, if you are a bidder and serious, he'll provide the vins and stamp pics. Again, I don;t know him and only had one conversation. Like any high dollar car, get it inspected if you are serious.
As long as the engine is real and the original, and can be verified by someone like Jerry, then I would imagine it would be ok? I would think that is better than a car w/o a matching engine, but paperwork?
