Making its debut in 1970, this car definitely turned heads. Modeled from a racing car’s chassis, the box-shaped frame sets this car apart from the pack. Via 24 holes inserted into its hood there's a clear view of the car's engine. With a sliding roof that offered easy access to the cabin, this Modulo was a true car of the future. So what was the Achilles’ heel? Since the wheels were built into the car’s frame, this Ferrari could only be driven in one direction – straight.
