Coggin worked as used car manager for Wood Chevrolet. His success led him to the presidency of the Birmingham Area Used Car Dealers Association and vice-presidency of the state association before 1953. That year he resigned from those positions to take up ownership of the Luther Coggin Oldsmobile dealership at 2012 Avenue E in Ensley, managed by his son, Luther Coggin, Jr. They moved the dealership to Five Points West in 1955. Luther, Jr, who at one time held a 25% stake in the dealership, left the business in 1963.
