12. Plymouth Superbird
Its towering rear wing and prolonged nose cone made the Superbird one of the wildest cars ever seen on American roads, resembling something that belonged on a lunar runway. Developed for NASCAR, the Superbird’s aerodynamic design included a pointed nose and a massive rear spoiler, enhancing its high-speed stability. Only 1,920 were produced in 1970, making it a rare and iconic muscle car. (motortrend.com)
