1948 Buick Series 70 Roadmaster Navigation
The 1948 Buick models continued to wear pre-war styling but despite the longevity, the designs remained popular with buyers. This particular top-of-the-line Buick wears convertible coachwork and is powered by a 320 cubic-inch Dynaflash straight-eight cylinder engine backed by an optional new-for-1948 Dynaflow automatic transmission. It currently wears a shade of Regency Blue Metallic, replacing the original Cumulus Gray paint scheme, with a red leather interior.
This Buick has a power front bench seat (now equipped with seat belts), power windows, power-operated convertible top, power brakes, an AM radio, clock, carpeted floor mats, and a heater. The chrome-ringed odometer currently displays 60,100 miles.By Daniel Vaughan | Dec 2021
