This is CM/3/63—the only original surviving Shelby Factory Team King Cobra, authenticated by Carroll Shelby himself. With a 289ci V8, four Weber carbs and 400hp, this car helped pave the way for the Ford GT40 and the Can-Am era. Raced by Holbert, Miles, Pabst and more, this King Cobra is a crown jewel of Shelby history—and it crossed the block at the 2014 Scottsdale Auction. How much do you think this legend sold for?
