6. BMW M1
BMW’s first and only mid-engine supercar, the M1, featured an ultra-low stance, pop-up headlights, and sharp geometric lines, reminiscent of science-fiction spaceships. Designed by Giorgetto Giugiaro, its wedge-shaped fiberglass body and distinctive rear slats contributed to its futuristic appeal. Rare and highly collectible, the M1’s radical look remains legendary.
