Bill Mitchell designed the 1972 Buick Silver Arrow III concept which made its debut at the 1972 Detroit Auto Show. This concept car was based on a production Riviera but featured several upgrades, such as a lowered roofline and redesigned quarter windows.
It also boasted advanced features like high level warning lights that served as secondary turn signals, six halogen headlights for better visibility during nighttime driving, and four wheel anti-lock brakes. Moreover, the Silver Arrow III was equipped with Max Trac, a technology that served as a precursor to modern traction control systems.
