The Buick Brand

Buick was founded by David Buick who began working with gasoline engines in 1899. Buick traditionally dates its beginnings to 1903 but prior to that built only three automobiles and had accumulated plenty of debt. In 1903 Buick was incorporated and moved from Detroit to Flint and then to Jackson, Michigan. Buick had many ups and downs financially and actually recovered from near bankruptcy in 1904. The future began to look better though, with at one time Buick being the No. 1 producer of automobiles in 1908. In that year Buick had more production than Ford and Cadillac combined. The automaker then caught the interest of William Durant who went on to acquire the firm forming General Motors with Buick becoming it’s top brand..
