The Holy Grail of Cobras. 1965 Shelby Cobra 50th Anniversary edition! Few if any cars of the 20th century inspire more passion than the famed Shelby Cobra, a name that has always been synonymous with racing domination since its introduction in 1962. Its successor, the Cobra 427 introduced in 1965, has fueled the dreams of generations of enthusiasts as the ultimate iteration of Carroll Shelbys creation. In late 2014, Shelby American announced the release of a special edition of the CSX4000 Series Component Cobra to commemorate the 427 big-block Cobras 50th anniversary. Only 50 were built, making them among the most exclusive of any machine to wear the official Cobra badge.
