It’s more heartache for the birthplace of Saturn in the town of Spring Hill, Tenn.

The failure of a deal for Penske Automotive Group Inc. to acquire Saturn from General Motors Co. led to GM saying Wednesday in Detroit that it plans to shut down the brand.

At Spring Hill, where GM launched Saturn about two decades ago, the surprise announcement creates uncertainty for about 50 employees at a Saturn parts distribution center.

Saturn was designed to compete with low-cost imports and developed a cult following that included carnival-like "homecoming" celebrations for owners.

United Auto Workers Local 1853 President Mike O’Rourke said the future of the jobs is uncertain and although the brand is no longer made in Tennessee, its demise "breaks your heart."
