My question was how much would the car be worth if it checked out not how to verify its authenticity but thanks for your "help".
So, a Warren County boy? There will be enough locals in the Cinncinati area who can help with identification as well as an opinion on value by looking at the vehicle in person. At this board, given the ad has identified it as something that was never produced at a GM factory, we cannot do so. Heck, is Paul Freese still in business in Batesville? He's more of a GTO guy, but he'll have an opinion.
