Buick was founded in 1903 by David Dunbar Buick and became a key component in the founding of General Motors by Billy Durant in 1908, known for early innovations like the overhead valve engine and popularizing the luxury car market, especially as the highest-selling GM brand for a period after Chevrolet's entry into GM. The company's tri-shield emblem, adopted in 1960, is still in use today, symbolizing the brand's enduring legacy of quality, performance, and elegance, which continues to define Buick as a premier luxury marque within GM.
