I don't know this car personally but have a friend, Ron McCall, who is a Pantera specialist and knows this car very well. Ron Is mentioned in the write-up about this car. He is a great down to earth guy and undoubtedly will be willing to give you honest information. His telephone number is 410-596 3170. He lives north of Baltimore, MD. I attached an image of one of Ron's Panteras, the one he races.
Feel free to use my name, Tom Kuester, I was at his shop last week with a friend who is having Ron tweak his Pantera.
I hope its as good a car as advertised. Good luck
