Auburn was a brand name of American automobiles produced from 1900 to 1937, most known for the Auburn Speedster models it produced, which were fast, good-looking and expensive. However, after the 1929 Wall Street Crash, and the economic downturn that ensued, Auburn's expensive automobiles, along with its also very expensive sister marques Duesenberg and Cord, saw inevitable sales downturns, and all vehicle business halted in 1937.

Duesenberg Automobile & Motors Company, Inc. was an American racing and luxury automobile manufacturer founded in Indianapolis, Indiana, by brothers Fred and August Duesenberg in 1920. The company is known for popularizing the straight-eight engine and four-wheel hydraulic brakes. A Duesenberg car was the first American car to win a Grand Prix race, winning the 1921 French Grand Prix. Duesenbergs won the Indianapolis 500 in 1922, 1924, 1925 and 1927. Transportation executive Errett Lobban Cord acquired the Duesenberg corporation in 1926. The company was sold and dissolved in 1937.
