Oldsmobile Ninety Eight in Context

Within the Oldsmobile range the Ninety Eight sat above the Eighty Eight as the senior car, riding a longer wheelbase and carrying more brightwork, richer trim and a longer list of standard equipment. Any Oldsmobile Ninety Eight overview has to see it as a General Motors prestige product placed just beneath Cadillac, aimed at buyers who wanted size and comfort without leaving the Oldsmobile showroom. The late fifties were years of annual restyling, so this generation reads as two closely related but visibly distinct designs.

Understanding 4 generation

Across Oldsmobile Ninety Eight generations the fourth is the short one, spanning only 1957 and 1958. The 1957 cars were lower and wider than their predecessors, while the 1958 restyle added heavier chrome treatment that has become a symbol of the era. Oldsmobile Ninety Eight body styles in this period were the Cabrio, the Coupe and the Sedan, all sharing the same long chassis. When reading Oldsmobile Ninety Eight dimensions, remember that the body style and the model year matter more than any single trim name.
