For me the model year doesn't matter. It's the history. A Camaro that competed in SCCA regional type production races will not get accepted to places like the Monterey Historics...the car has to have verified Trans Am history, not just SCCA history. Many cars that competed in SCCA are oftened times passed off as Trans Am vintage elgible and they are not.
There is a base value on these old race cars and then it can go up depending on what races the car competed in, who drove it and what kind of finishes it had. I don't know much about that 1968 car but I would suspect if someone paid 110k un restored for the car it has good history. Personally I would like to have both
Still the 69 UOP car fully restored and ready to go seems like a better deal.. in the end niether will , or have , had a problem finding a new home . Both very cool cars.
I don't even want to think about how much money it would take to get the Sunoco 69 Camaro out of Ken Eppsman's hands.. I am not sure any number would do.
