Description

The Buick 120 Series Master Six Sedan, produced during the early 1930s, was a distinguished example of Buick’s commitment to quality, performance, and luxury in the pre-war American automobile market. It belonged to the “Master Six” range—so named for its smooth and powerful inline six-cylinder engine—and was positioned as a more upscale offering within the Buick lineup, appealing to buyers who valued both reliability and refinement.

Under the hood, the 120 Series Master Six was equipped with a robust straight-six engine that provided around 70 to 80 horsepower, depending on the specific model year and tuning. This engine was known for its smooth operation and durability, traits that made the car especially appealing during a time when buyers were looking for value and longevity in their vehicles. Power was delivered to the rear wheels via a three-speed manual transmission, and the driving experience was enhanced by Buick’s advanced engineering, including mechanical brakes and a solid suspension system suited to the road conditions of the era.

The body of the Master Six Sedan was both stately and conservative in appearance, in keeping with Buick’s image of understated elegance. It featured a long, sweeping profile with rounded fenders, a tall upright grille, and dual side-mounted spares in some versions. The car typically sat on a relatively long wheelbase, which contributed to a comfortable ride for both driver and passengers.

Inside, the sedan offered a well-appointed cabin with plush cloth upholstery, wood-trimmed details, and a spacious rear seating area. The dashboard was simple but elegant, with gauges neatly arranged for easy visibility. While features were modest by modern standards, the attention to craftsmanship and comfort was evident throughout.

The Buick 120 Series Master Six Sedan stood as a symbol of middle- to upper-class aspirations during the Great Depression, offering style and sophistication without the extravagance of more expensive luxury marques. Today, surviving examples are appreciated by collectors for their classic lines, strong engineering, and the grace with which they represent Buick’s golden age.
