Radically re-designed in 1971 the Riviera featured a flowing boat-tail style penned by future Nissan stylist Jerry Hirschberg under the direction of icon Bill Mitchell. Some say there was '1963 Corvette split-window coupe' in every one. The 'Riv' was GM's E-body 'big car' platform related to both the Cadillac Eldorado and the Oldsmobile Toronado.

This car is a rare Stage One which in 1973 meant 260 horsepower, a limited slip differential and chrome-plated air cleaner. Gran Sport meant a rear stabilizer bar, whitewall radial tires with appropriately 'tuned' suspension to suit, and additional sound insulation. For 1974 the model went with 'conventional' styling.
