21. Chevrolet Monza Mirage (1977)
The Chevrolet Monza was introduced in 1975 as the newest GM compact model with modern design, good equipment, and a wide arrange of versions and trim levels. The Chevy contracted an outside company called Michigan Auto Techniques to make a muscle car for 1977. Called the Monza Mirage, this one-year model was produced in a somewhat respectful 4,000 examples and featured a 305 V8 with just 145 HP. The design was quite striking with a white body, front and rear spoilers, and unique wheels (via Hip Rides).
The paint scheme was patriotic, with red, blue, and white stripes. Chevrolet realized that there was still a market for sporty variants and decided to introduce Monza Spyder for 1978, leaving Michigan Auto Techniques without the contract for 1978 and sending the Monza Mirage to the history books. Today, only a handful are known to survive. If you find one, try to buy it and restore it since it is a rare and forgotten muscle car.
