Founded in 1899 by Scottish‑born inventor David Dunbar Buick and officially established as the Buick Motor Company in 1903, Buick produced its first car, the Model B, in 1904, featuring an innovative two‑cylinder engine . Buick helped spark the creation of GM under William C. Durant in 1908 . Known for its premium positioning, iconic Trishield logo (rooted in Buick’s family crest), and innovations like the first concept car and overhead‑valve engines, Buick is the oldest surviving American automaker .
