On Bristol Road in Swartz Creek, it opened in 1957. It merged with other car divisions' parts operations in 1969 and was renamed the GM Parts Division (later Warehousing and Distribution). During the late 1990s, GM's worldwide parts purchasing and distribution office headquarters moved from here to a new building in Grand Blanc Township. Known as Service Parts Operations-Flint, the Swartz Creek facility remains open with a large amount of vacant office space. Currently, 595 hourly and 70 salaried workers are employed at SPO Flint. In May 2014, GM invested $10 million in upgrading the appearance and quality of the plant.
