This is an example of a beautifully, heavily customized and modified car. But it isn't, nor could it ever be a GT5.
It is a Euro 1973 with stuff bolted/molded added to it. GT5 cars weren't even being made in 1973. The info contained on your link suggests that your Euro'73 is a rarity.
Rare compared to the thousands of modified Panteras out there? Not really.
