Buick Standard Six
The Buick Standard Six Series 20 was an automobile produced by Buick between 1925 and 1928. Powered by the overhead valve Buick straight-6 engine, it was the junior model to the Buick Master Six, and shared the GM A platform with Oldsmobile, Oakland and Chevrolet. The Standard Six evolved from the earlier Buick Six when the Buick 4-cylinder was cancelled.
The Standard Six was the most popular Buick sold while being more upscale to the Oldsmobile Six. It was the senior brand to Marquette under the General Motors Companion Make Program until Marquette was cancelled one year later. It replaced the earlier Buick Six that was introduced in 1916, and was replaced with the Buick Series 50. Coachwork continued to be offered by Fisher Body, which was the primary supplier of all GM products at this time, and its Duco automotive lacquer paint, introduced by DuPont was the first quick drying multi-color line of nitrocellulose lacquers made especially for the automotive industry. The Series 20 was manufactured at what would later become known as the Buick City factory on Hamilton Ave. in Flint, Michigan.
