Oldsmobile Supreme
The Oldsmobile Cutlass Supreme was a mid-size car produced by General Motors for the American market. It was always at the top of the Cutlass range. It began as a trim package, developed its own roofline, and eventually was mechanically divorced from the later, smaller Cutlasses. The Cutlass Supreme was only offered as a four-door hardtop sedan (Holiday Sedan) in 1966. For 1967, the Cutlass Supreme line was expanded into a full series that also included a two-door hardtop coupe (Holiday Coupe), two-door pillared coupe (Sport Coupe), four-door pillared sedan (Town Sedan) and a convertible. In 1967, the high-performance 442package with the 400 cubic-inch 350 horsepower (260 kW) V8 was available on three Cutlass Supreme models including the sport coupe, Holiday coupe and convertible. The Cutlass Supreme name lasted from 1966 until 1997.Oldsmobile Supreme FAQ's
