Lansing Car Assembly was a General Motors automobile factory in Lansing, Michigan. It contained two elements, a 1901 automobile plant in downtown Lansing, and the 1920 Durant Motors factory on Lansing's Far Westside. From the 1940s through the 1980s, it was the main producer of full-size Oldsmobiles (88 and 98), but by the 1990s it was producing compact cars for several GM divisions.
