Lot's of pictures on ProvaMo - I don't know if that helps you a lot, because you probably don't have pictures to share to get access, but.... if you can get access, you might want to check out some of the older pictures posted there.
It looks like this car has spent a long time in a storage container in Washington.
Looks very original, and it certainly shows well on the outside.
Good Luck - maybe you should consider either joining POCA, and check with the Pantera's Northwest chapter, or see if you can find someone on this board in the local area of the car to go and check it out for you.
My recommendation (after seeing the pictures) is that you would really want to have someone who knows what they are looking at to thoroughly go over the car before you put any money down.
I'm not saying anything good or bad about this car - I know nothing about it. It may be a smoking deal.
Good Luck -
