20. Ford Mustang Mach II
The success of the production model gave Ford designers a chance to explore the sports car concept in any direction. As soon as the first redesign of the car appeared in 1967, Ford introduced the Mach II concept. This was one of several cars with the Mach name that would later appear as regular production versions, but the shape and layout were quite unique.
The Mach II was a two-seater sports car with a long hood and short rear end as well as the mid-engine configuration. The car was a more affordable version of the GT40 race car and was stunningly painted in red with Shelby-style alloy wheels. Unfortunately, they never produced the concept, so the Mach II only served as a car show item.
