Car: Ford Mustang Mach 1 ( Sportsroof )
What makes it special: The Mustang Mach 1 was introduced in August of 1968 as a new package for the 1969 model year.
What made it famous: The Mach 1 was so successful for it's debut in 1969 that Ford discontinued the Mustang's GT model the following year. ( The "GT" badge returned in 1982 ) The Mach 1 package was only available in the "Sportsroof" body style (which was previously known as a "Fastback"), and never available on the Coupe or Convertible.
Why I would want one: The available Mach 1 V8's ( from a 351 to 428 Cobra Jet), plus the obvious visual and performance items: A matte black hood treatment with hood pins, hood scoop (including optional Shaker scoop), competition suspension, chrome pop-open gas cap, magnum wheels on Goodyear Polyglas Tires, chrome exhaust tips, dealer optional chin spoiler, rear deck spoiler, and rear window louvers...just to name a few of the reasons.
Fun fact: Ford first used the name "Mach 1" in its 1959 display of a concept "Levacar" called the Ford Rotunda. This concept vehicle used a cushion of air as propulsion on a circular dais.
