Few things are as quintessentially American as baseball, apple pie, and hot dogs. One of these is Ford’s Mustang. Introduced in 1964, the Mustang is currently enjoying its 50th Anniversary. With the eminent launch of the all-new 2015 Mustang, let’s take a look back at some of the special edition Mustangs produced over the years. While Ford’s Mustang team has produced many of them in-house, a handful of aftermarket manufacturers have produced some highly notable ones as well. One such manufacturer, Carroll Shelby, was so successful at it, Ford named the highest performing variant of the Mustang ever produced for him, even though the engineering was done at Ford.
