I think that I know this Pantera. It was in a "salvage yard" in Atlanta around 1983. They wanted something like $15,000 for it then. At the time you could get an entire new exterior shell from Hall for $18,000. All factory original parts.
I'm not aware of anyone who bought it. It might still be there? The stack of wrecked Gr4 factory cars that I saw were in about 1000% better shape then this thing.
The Cosby Cobra, after it was driven off of a cliff was better too. I'm not sure how a car can get wrecked this badly?
