Larry said that the Corvette has been unrefined since 1968. I don't think of either early or later model Corvettes as being particularly refined.
I do know that if a 1967 or earlier Corvette driven by a comparable driver were to try to keep up with this new one here, it would be a sad thing to see as it was completely blown away by the newer model.
Never, ever again will I own one unless it is a gift or a "prize", and the plan would still be to sell or trade it. That includes the Corvette, of any year model ever made.
