Mayse Automotive Group

Buick has been a product innovator from Day 1 -- starting with its creation of the overhead valve engine (later advertised by Buick as the valve-in-head engine) which earned an unsurpassed early reputation in competition around the world. 

From the beginning, "motor" has been a key word in Buick's name. That original patented overhead valve single cylinder was unbelievable for its time.  It was powerful, reliable, and developed more horsepower with its displacement than other engines of like size then on the market. Eventually the entire industry would make use of the principle.
