Designed by Jerry Hirshberg, the 1971 Riviera broke away from Buick's conservative look which had been associated with their previous cars. It was bigger and heavier than previous models, but the dramatic styling which brought the car to a point at eight ends, more prominent at the rear, led to the car being nicknamed the 'boat tail Buick'. It rode on a separate perimeter chassis, with an independent wishbone front and live axle rear supported on coil springs. The Gran Sport package meant stiffer springs, revised shock valving, and a thick front anti-roll bar, With fuel at just 30 cents a gallon, Buick had no qualms putting in their 455ci (7.5-liter) big-block engine, which with its long stroke made a lot of torque and the car more of a luxury cruiser than straight-line performer. The car lived for just two years before being re-styled, then dropped altogether.
