13. Caterham 7

The Caterham 7 is an icon of minimalist automotive engineering, stripping away almost every comfort and safety feature imaginable.
Its featherweight build and intense performance make it more like a street-legal go-kart than a traditional car. With little crash protection and a demanding driving style, it’s easy for inexperienced drivers to get in over their heads.
While thrilling for enthusiasts, the Caterham 7’s sparse design leaves many questioning its place on public roads.
