This 1963 pre-production Mustang is basically the same car that would be introduced as the 1965 Mustang. This particular car was altered and exhibited at a number of auto shows. It is a convertible equipped with removable fiberglass top, 289-cubic inch, high performance, Cobra-modified engine and four-speed manual transmission.
The second X-Car, the Mustang II, was also based upon the Falcon/Comet/Fairlane platform and enjoyed a lithe body designed by Joe Oros. Despite its name, however, it carried few styling and design cues from the Mustang I. The pearl white experimental car, first displayed at Watkins Glen in September 1963, played an important role in the public reception of the X-Cars and was presented to the auto enthusiast press as a direct precursor to the production Mustang that debuted in April of 1964. Also built on a Falcon platform, it displayed all of the production Mustang styling cues that would appear on the production car. A toned-down front end, a modest bumper, a raised roofline, and a slightly revised dashboard and modestly reshaped rear quarter panels were almost the only design elements to distinguish the production vehicle from the concept car.
