 After Buick ceased building rear-wheel-drive cars and Buick City got underway, BOC Flint Body Assembly earned a reprieve by building bodies which were shipped to GM assembly operations in Pontiac, Michigan until the plant closed in December 1987.Most of it was demolished in 1988, except for portions which were gutted and transformed into the Great Lakes Technology Center; the original administration building remains intact.GM initially had substantial office and engineering operations at the GLTC (including AC Rochester world headquarters), but eventually transferred those staffs elsewhere.
