It was a two-level plant located in the Canton Industrial Center to the east of the Inner Harbor, to the west of Dundalk, and south of Brewers Hill in Baltimore.

Early in 1942, car and truck production was interrupted when the plant was converted to wartime activities.

The versatility of the plant was tested in 1964 when Buicks, Chevrolets, Oldsmobiles and Pontiacs were assembled one after another on the same passenger car line.

The rival Dodge Caravan was selling briskly, but the truck-like GM vans were larger than most of the mini-vans then coming into production.

The vans were periodically updated with revised interiors and exterior styling during the very long production run.
