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 plant ceased production of full-size Pontiacs after the 1980 model year, and was idled on August 6, 1982.
Another production line was opened in 1983 to build the Fiero. The old production line was reopened January 14, 1985 to build the GM "G" body Oldsmobile Cutlass Supreme and Buick Regal, as the Lansing and Flint plants which built them had been converted to new front-wheel-drive car lines. Chevrolet Monte Carlo production was added for 1987. Production ended on December 11, 1987. Fiero production ended on August 16, 1988, and the plant was permanently closed. Manufacturing operations were transferred to Orion Assembly.
