Pontiac Assembly was one of four General Motors assembly plants in Pontiac, Michigan located along Baldwin Avenue. It served as the main facility for Pontiac Motor Division since it was built in 1927. It is across the street from the currently operational Pontiac Metal Center, which was the original location for the Oakland Motor Car Company, which Pontiac evolved into. The location that Oakland inhabited was the original site of Cartercar when GM bought the company in 1909 by William Durant. The plant ceased production of full-size Pontiacs after the 1980 model year, and was idled on August 6, 1982.
