Barley Motor Car Co. was a manufacturer of automobiles in Kalamazoo, Michigan and Streator, Illinois. It manufactured the Roamer automobile (1916–29) and, briefly, the Barley (1922–24), and the Pennant (1924–25). The Roamer was marketed from its inception as "America’s Smartest Car." It was also successful in many early racing events. After a Roamer with a Rochester-Duesenberg engine set six records for one kilometer, one-, two- three-, four- and five-mile sprints at Daytona Beach in 1921, the advertisements crowed, "America’s Smartest Car Makes America’s Fastest Mile."
