Flint, Michigan is a city which previously relied on its auto industry, and still does to an extent. Over the past several decades, General Motors plants in Genesee County have experienced re-namings, management shifts, openings, closures, reopenings, and spinoffs.
General Motors traces its roots to the Durant-Dort Carriage Company of Flint, and purchased the original Durant-Dort factory (built in 1880 as a woolen mill) on Water Street in May 2013 (and the Durant-Dort office, a National Historic Landmark across the street, as well). The company will take over responsibility for maintenance from the Flint Historical Foundation.
On Hamilton Avenue, the oldest buildings opened in 1908. This was the largest GM complex in the world. Buick originally opened in Flint on West Kearsley Street; this plant was repurposed as the first Chevrolet factory after the Hamilton Avenue site opened.
In 1983 Buick announced plans for Buick City (inspired by Toyota's "Toyota City" plant), which would combine Buick's assembly and Fisher #1's bodybuilding operations. The production of rear-wheel drive cars at Buick's Hamilton Avenue plant ended. After gutting the interior, installing robots (and other retooling), and the construction of a new body shop and just-in-time delivery docks, Buick City began building front-wheel drive vehicles in 1985.
Buick Motor Division became a marketing and public-relations entity in 1984, when the Buick-Oldsmobile-Cadillac Group (BOC) was created and took over engineering and assembly control from Buick, Oldsmobile, Cadillac and the GM Assembly Division. GM created the Flint Automotive Division to manage BOC's activities in Genesee County, which included the former Buick factories and engineering. BOC dissolved in 1992, and eventually its functions were transferred to the Cadillac/Luxury Car Division (not to be confused with the Cadillac Motor Car Division, the traditional Cadillac operation).
