What US state was the home of General Motors' original "Saturn" automobile plant?

The Saturn Corporation, also known as Saturn LLC, is a registered trademark established on January 7, 1985, as a subsidiary of General Motors. The company marketed itself as a "different kind of car company" and operated somewhat independently from its parent company for a time with its own assembly plant in Spring Hill, Tennessee; unique models; and a separate retailer network, and was GM's attempt to compete with Japanese automakers.

On July 30, 1990, the first Saturn was built, a red 1991 Saturn SL2.

Results at Saturn, however, were more doubtful than positive. According to The Wall Street Journal, the project was too ambitious, as "everything at Saturn is new: the car, the plant, the workforce, the dealer network and the manufacturing process". Not even Toyota, a highly successful and experienced automaker, tackles more than two new items on any single project.

Saturn was believed to have had a disagreement with GM and were not very accepting of the company closing. In 2004, GM and the United Auto Workers dissolved their unique labor contract for the Spring Hill manufacturing plant, allowing Saturn operations to be integrated with the rest of GM. All new production was halted on October 7, 2009.
