The company was founded in Michigan in 1911 by Louis Chevrolet, a Swiss pilot, and by William C. Durant, founder of General Motors from which he was ousted due to his debts. Chevrolet immediately produced a model in direct competition with the Ford Model T which was called Classic Six. In 1917 William C. Durant returned to take over General Motors, and incorporated the Chevrolet to it. The "Chevy" had a great influence in the American automotive market, especially in the fifties and sixties. In 1963, one in ten cars sold in the United States was a Chevrolet.
