In 1978, the Pontiac Grand Prix was downsized, along with its corporate cousins, the Oldsmobile Cutlass Supreme and the Chevrolet Monte Carlo. And the Buick Regal, of course, which I covered previously here at RG.
Phase II of General Motors’ downsizing had begun. The Colonnade midsizers of 1973-77 were but a memory, and Bill Mitchell’s Sheer Look, pioneered by the 1976 Cadillac Seville, was applied to all A-bodies, including the A-special GP and Monte.
