14. Ford Mustang Mach I Concept
Ford presented this car at the 1966 Detroit car show. Immediately, it became one of the most interesting models even though it was just a prototype. The Mach I was the first sporty and muscle Mustang Ford released. Interestingly, it showcased a 1967 redesign with its sexy Fastback lines. However, Ford also chose a new name to use in 1969.
With a chopped roof, square headlights, Plexiglas side windows with racing-style cut-outs, cool wheels, and beautiful burgundy color, the Mach I was a muscle car Mustang at its finest. And soon, it captured the imagination of car enthusiasts all around the globe. Even today, the Mach I is one great-looking car.
