Yellow oldtime car Checker. Checker Motors Corporation was a Kalamazoo, Michigan. Checker Motors Corporation was established by founder Morris Markin in 1922. Checker made the iconic American taxi cab, valued by taxicab companies for its durability in heavy use. Special features included wide rear doors, large rear seats and trunks. The company had trouble competing with fleet discounts offered by the larger manufacturers, as well as economies of scale in procuring components. The final models were produced in 1982.
