 It was originally based on the platform of the second generation North American Ford Falcon, a compact car.
 The original 1962 Ford Mustang I two-seater concept car had evolved into the 1963 Mustang II four-seater concept car which Ford used to pretest how the public would take interest in the first production Mustang.
 The 1963 Mustang II concept car was designed with a variation of the production model's front and rear ends with a roof that was 2.7 inches shorter.
 Introduced early on April 17, 1964 (16 days after the Plymouth Barracuda), and thus dubbed as a "1964½" by Mustang fans, the 1965 Mustang was the automaker's most successful launch since the Model A.
 The Mustang has undergone several transformations to its current sixth generation.

 He joined forces with retired Chrysler stylist Virgil Exner who designed the new Blackhawk.
 Exner's design included a spare tire that protruded through the trunklid, a massive 'kidney' grille, and freestanding headlamps.
 The new Blackhawk was prototyped by Ghia in Italy at a cost of over US$300,000.
 To offer exclusivity and still allow easy servicing in the US a custom built Italian body was added to a GM platform and engine.
 The Blackhawk debuted in January 1970 at the Waldorf Astoria in New York City.
 Prices ranged from US$22,500 to US$75,000.
 All early Blackhawks were coupes, but rare sedans were produced later.
 Convertible versions were called "D'Italia" and "Bearcat".
 Stutz Blackhawks became the car of choice among elite entertainers of the day.
 By 1976 Stutz had sold 205 Blackhawks and about six a month were handbuilt in Italy and shipped to the US.
 By April 1980 350 Blackhawks had been sold and by the time production ended in 1987 approximately 500 to 600 cars had been manufactured.
