Here s one hell of a conceptual design: the Cadillac World Thorium Fuel concept. Otherwise known as the Cadillac WTF. It was created by Loren Kulesus. Everything about the aptly named WTF has been created to last for 100 years without maintenance.
West Coast Customs took a 2012 Ford Mustang and retrofitted it with a 1967 Mustang fastback replica body. They painted the car matte black, and decked it out with neon blue lights in the grill and around the rims. Love the Neon blue light
