Hi Bob,
(In general) As I've said before, and at the beginning of the Registry pages, the cars listed, are done so without any guarantee of complete authenticity. Just because it's been listed in the 1989 and 1996 GT/CS Registries, it is not grounds for complete authenticity. So--look for the Marti Report (or orig. paperwork and build sheet, invoice, etc.) when buying a GT/CS.
Before the advent of the "Marti Report", I relied on people's honesty; or at least their knowledge of authenticity.
I don't have the luxury of the Shelby access to records like SAAC, nor do I have access to Ford's records--which is exclusive to Kevin Marti--at great cost.
We couldn't get all the VIN numbers, so, we're kinda on our own. I will include a column of those cars with Marti Reports that authenticate a true GT/CS or HCS in the new Registry.
Paul.
