1968 Chevrolet Corvette Stingray C3

Based on the Mako Shark concept, the Corvette’s late-’60s makeover is largely defined by its long, pointed nose and fat tyres – at eight inches wide for 1969, the largest on any car at the time. Coupés started to outsell convertibles, so the latter are now worth around 25% more. Once again, engines come in a variety of big and small-block options, with outputs ranging from 300-435bhp. Our prices are for the former – expect double for the latter and fill the gap with anything in between. Emissions regulations put the squeeze on power from 1971.
