The one-of-one Mustang Bertone was created when Automobile Quarterly publisher L. Scott Bailey suggested that the brand new Ford Mustang would make an ideal canvas for the renowned Italian design house of Nuccio Bertone. (The car’s lead designer was a young Bertone stylist named Giorgetto Giugiaro.) Shown once in America at the 1965 New York Auto Show, the Mustang Bertone hasn’t been seen since, but rumors abide that the car still exists.
