When you say "no rust" did you inspect the car personally and look at all the typically problem areas? Did you test all the electrical components e.g. lights, wipers, etc? The electrics on these cars can get a little squirrelly. I don't know where you stand on the purchase but you might want to post a request looking for a Pantera owner in Ga. to look at the car. Do you have a VIN? Someone might know the car.
