The Old Lincoln plant was located at Warren & Livernois in Detroit. After Ford built the "New" plant in Wixom it was sold to Detroit Edison and became the Warren Service Center which it still is today. I work for DTE/Detroit Edison and have to go there quite frequently. A very small portion of the old assembly plant still exists and is used as Maintenance and Fabrication Shops. While the large office building shown in that picture is gone, a smaller office building to the right of that main Admin building also still exists, but everyone has been moved out of it and it is scheduled to be demolished soon. If you know where to look and what to look for, you can still see some traces of the Ford heritage with the existing buildings.
