The Glasspar G2 was in the same situation as the Wildfire. I was ready to argue that Glasspar made only boat hulls, but they apparently built a car called the Glasspar in 1949. Both had a few units made but then the rest of the cars were kits. Yes, some were produced, but they were not produced like the Corvette was, though they say that the body for the Wildfire was of a higher quality than the 'Vettes! You learn something new everyday...
