It doesn't help discern where it is now, but given the serial number this is likley an 80/81 Pantera, possibly a GT5 that had limited sales routes into the US at the time. Perhaps it was a George Stauffer imported car, although Robert was likely not the first owner having acquired it in July 1985.
Off topic a little, but I have just increased insured values of my cars in line with the market, make sure you have enough coverage to replace you Pantera should the worst happen.
