Saturn Corp. says it is not participating in a program by parent company General Motors Corp. offering rebates of up to $800 to military personnel on new GM vehicles because its pricing structure cannot afford it.

"We don't think we're being un-American," company spokesman Mark Tanner said. "It is just that our pricing strategy does not include any options for general discounts or retail incentives."Tanner said Saturn declined a request by GM to participate in the offer, which runs until the end of 1991.

Saturn's cars start at $7,995 for a basic four-door sedan and range up to just over $16,000 for a fully equipped SC coupe. Tanner said Saturn cars have recently been selling at or near sticker price through its current network of 62 dealers.

The company began building cars late last year at its $1.9 billion complex in Spring Hill, Tenn.

GM announced this week special rebates to all active-duty U.S. military personnel or their spouses on a new GM vehicle through Dec. 31.

Starting immediately, all eligible buyers will be entitled to a $300 discount when they finance their new GM car or light truck through the company's financing operations. It will also match up to $500 of the purchaser's own down payment, bringing the potential savings to $800.
