Oldsmobile 98 was part of the Series 90 and was powered by an 8-cylinder engine. This full-size automobile, which served as a flagship model for the Oldsmobile (a GM division) got its name through these specifications. The 98 had the same General Motors C-body platform as the Buick and Cadillac. As a high-end model, it was well equipped with advanced technology features such as an automatic headlight dimmer known as the Autronic Eye, the Twilight Sentinel, which automatically turned the headlights on and off via a timer, and the Hydramatic automatic transmission.
