Pontiac Grand Ville, 1971. Launched as a new flagship model for the Pontiac range built on a stretched-wheelbase version of the GM “B” platform, the Grand Ville was initially available as pillarless saloon or coupe and a convertible. All were powered by the 455ci V8 with Turbo-Hydramatic automatic transmission. Initial sales were strong and built to a peak in 1973 but 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 and the Grand Ville was discontinued in 1975.
