Description
The Buick Roadmaster 70 Sedan was a top-tier model in Buick’s lineup during the late 1930s and 1940s, representing a blend of luxury, performance, and advanced engineering. The “70” designation identified it as part of the prestigious Roadmaster series, which stood just below Cadillac in General Motors’ hierarchy, making it one of the most desirable Buicks of its time.
Introduced in the late 1930s and continuing into the early 1940s, the Roadmaster 70 Sedan featured a large, imposing body built on Buick’s longest wheelbase platform at the time. This extended length allowed for a spacious and luxurious cabin, providing comfort for both front and rear passengers. The four-door sedan body style offered practicality, while the elegant curves, sweeping fenders, and a bold, chrome-accented grille reflected Buick’s sophisticated design philosophy of the era.
Power came from Buick’s 320 cubic inch straight-eight engine, an overhead valve design that was known for its smooth power delivery and durability. This engine produced strong torque, making the Roadmaster a capable highway cruiser. It was mated to a three-speed manual transmission, and starting in the late 1940s, some models were available with Buick’s Dynaflow automatic transmission, which further enhanced its smooth and effortless driving experience.
The interior of the Roadmaster 70 Sedan was among the most refined offered by Buick at the time. High-quality materials such as mohair or broadcloth upholstery, woodgrain dash trim, and thick carpeting were standard. The dash was equipped with large, stylish gauges and chrome accents, reflecting the car’s upscale nature. Passenger amenities included ample legroom, soft suspension for a comfortable ride, and good sound insulation, all contributing to a premium driving environment.
As a luxury sedan, the Buick Roadmaster 70 was favored by professionals, executives, and those who wanted a high-end American automobile that delivered both prestige and practicality. Its size and refinement made it ideal for long-distance travel or city driving with a touch of class.
Today, the Roadmaster 70 Sedan is a highly collectible piece of Buick’s history. Its elegant design, strong engine, and place as a flagship model make it a standout example of prewar and early postwar American luxury motoring. Restored examples are prized for their presence, comfort, and the craftsmanship that defined Buick’s golden age.
