is synonymous with gorgeous cars. Even before the legendary XKE debuted at the 1961 Geneva Motor Show, models such as the XK120 graced the world with its striking presence and sheer beauty. Launched in 1948, it was the world's fastest car. "120" referred to its top speed: 120 mph. The first cars were hand-built with all-aluminum bodies, but due to increased demand, Jaguar was forced to replace them with steel-pressed bodies. The doors, hood, and trunk lid, however, remained aluminum.
