David Buick first produced motor cars under the name of Buick Manufacturing Company in 1901. However the company was sold to the Briscoe brothers who established the Buick Motor Company, which was subsequently sold on in 1904. The managing director of the Buick Motor Company established General Motors in 1908. Buick was one of the founding members of the group. Buick got off to a slow start, selling only 21 cars in 1904, but by the time David Buick left his company in 1906 was producing (and selling) automobiles in increasing numbers. Numbers shot up from 1400 in 1906 to 30,500 in 1910.
