Some cars have a history. Some cars have a history that is so important they could be considered national treasures. OKV2 was the lead car for the factory Jaguar team at the 1954 Le Mans and was considered a heavy favorite to win — which it didn't do. The car was driven by Sir Stirling Moss and went back to the factory to become the development car for next year's race — which Jaguar won, along with the '56 and '57 races. A technical achievement and one of the most important cars in motoring history, D-Type OKV2 is expected to bring over $12 million at auction.
