The Pontiac Grand Ville is a full-size car that was a sub-series trim package for the Pontiac Bonneville from 1971 to 1975, which had served as Pontiac's top-trim model since 1958 while remaining below the top level Pontiac Grand Prix. The Bonneville name remained, and the Grand Ville replaced the Pontiac Executive name. The Grand Ville and Bonneville shared a number of trim and design elements that distinguished them from the Catalina, and the 1971-72 Grand Villes were built on a stretched-wheelbase version of the GM "B" platform that nevertheless had identical interior dimensions to all other full-size Pontiacs. In addition to more luxurious interior trimmings, the Grand Ville had distinctive chrome trim at the front and rear to set it apart from the rest of the Pontiac line. For 1974 only, the Grand Ville had unique parking lights which wrapped around the corner of the front fender. The car was often sold with deluxe appearance options, such as sport wheels and vinyl tops. Rear fender skirts were featured on the 1973 to 1975 models. Standard equipment on Grand Ville models included a 455 cubic-inch V8 (for 1975, a 400 cubic-inch V8 was standard and the 455 optional), Turbo-Hydramatic automatic transmission, power steering and power front disc brakes. Popular options included air conditioning, power windows and driver's seat, tilt steering wheel, cruise control, AM/FM stereo with tape deck and much more. One of the rarest options available on Grand Villes and other full-sized Pontiacs during this period was the adjustable brake and accelerator pedals offered from 1974 to 1976. The Grand Ville enjoyed moderate success from 1971 to 1973. However, the oil crisis of late 1973 and early 1974 led to gasoline shortages, long lines at filling stations, and high fuel prices. These factors sharply cut into full-sized car sales in 1974 as buyers moved towards smaller cars. For 1975, the Grand Ville became the Grand Ville Brougham and included more standard equipment than in previous years, such as power windows and a carpeted trunk. This would be the final year for the Grand Ville series, which included Pontiac's last convertible until 1983. For 1976, the Grand Ville nameplate was dropped and the lineup was renamed Bonneville Brougham, returning that nameplate back to its former full-size top trim level status. Grand Ville convertibles were rare, with production never exceeding 5,000 units per year during the model run. From 1973 to
