Late 60s vetted are the real deal. Tiny car, big 427. My dad had one that would bring the right front tire almost a foot off the ground when he stood on it. He flipped it off a bridge up near GSMNP and landed upside down in a creek. Split his face from between his eyes down almost to his Adam's apple...right down the middle. He lived though, and even after they pulled it out of the creek he was able to trade it for 2 used Volvos...lol...1 for him and 1 for my mom. His ears had both filled up with blood and he was still unconscious when he got to the hospital, so they called my grandparents (rip) and told them to come say their goodbyes. Turned out he just had a broken jaw and a 10 inch split down the middle of his face. He was fine in a month or 2, other than scars. Him and my uncle, who had and still has a GTO with the judge package, had some really sweet rides back in the day.
