Saturn of Indianapolis closes today, attributing its demise to the collapse of General Motors’ attempt to sell the brand to Penske last month.

President Lynn B. Kimmel said in a letter to customers than the inventory and employees at the 5333 Pike Plaza Road location are shifting to owner Lockhart Automotive Groups’ other dealerships — including Saturn of Fishers and Saturn of Greenwood.

“By now you have probably heard the news about the failed deal for the Penske Auto Group to purchase Saturn and that General Motors will be closing down the Saturn brand,” Kimmel wrote.

She cited “circumstances beyond our control.”

It was the only Saturn dealership in Marion County. She said it will be “business as usual” in Fishers and Greenwood and that owners who have questions or concerns can call her at (317) 594-7911.

Dealership operator Penske Automotive Group announced last month that it had abandoned plans to acquire the Saturn unit.

As a result, GM said it will wind down the brand and dealer network, potentially putting 13,000 Saturn dealership jobs at risk.

The announcement came nearly four months after Penske agreed to buy the rights to the 19-year old brand from GM when the automaker was in bankruptcy.
