About Chief Pontiac. He was a man of power and strength, a man of peace, a man whose word was his bond. He was Pontiac, Chief of the Ottawa Indian tribe, who lived from 1720 to 1769. Chief Pontiac was rugged, yet charismatic; strong, but gentle; a warrior, as well as a diplomat.
Most of Pontiac's models built during the 1960s and 1970s were either styled like, or were siblings to, other GM makes (except Cadillac). However, Pontiac retained its own front and rear end styling, interiors, and engines.
