The 1977 GM Phantom experimental car was the creation of former GM styling director William L. Mitchell. Unlike most experimental cars that flaunt a new styling idea or introduce a revolutionary concept to the car-buying public, the Phantom was simply a personal expression of its designer. Mitchell started with a Pontiac Grand Prix chassis and moved the seats and controls to the rear, giving the long-hooded car a rakish look. A variety of European influences are found on the 2-seater, including the use of chrome to wrap under the front fenders, wide chrome molding and high fender lines. Note the big conical wheel discs.
