Elements of the 235-acre (950,000 m2) complex dated from 1904, where all aspects of Buick vehicles were constructed, and it became known as Buick City in 1985. Operations ceased completely in 2010. The site was vacated by GM employees and site responsibilities were transferred to Motors Liquidation Company as of December 6, 2010. The final cars built at Buick City were the Pontiac Bonneville and the Buick LeSabre. Manufacturing operations were transferred to Orion Assembly.
