History of the 1958 Oldsmobile Ninety Eight

The Oldsmobile Ninety-Eight was a full-size vehicle introduced in 1941 and continued in production until 1996.  Oldsmobile’s 1958 models were powered by its Rocket V-8 that rightfully holds a position of tremendous stature in American performance history.  The 98 convertible wasn’t Oldsmobile’s most popular model for 1958, with a total output of only 4,504 units, but Olds was the top seller in its class and the 98 convertible was one of its crown jewels.

“Olds for 1958 is the epitome of good taste: Majestic, with an unmistakable look of luxury…” boasted the sales brochure. It was backed up by an ample array of new features, previously not available such as a power top, power windows, A/C, auto-dim headlamps, power antenna, power brakes, power steering, and six-way power seats. Another futuristic option was the sentinel speed warning alarm allowing the driver to set the speedometer to an alert signal when set speed was reached. Its “transportable” radio also provided music wherever you go by allowing its removal and independent operation via a 160-hour battery.
