(January 11, 2010) General Motors sent its clearest signal yet today that none of the bidders for Saab had submitted an offer that would prompt the automaker to reverse a decision to shut down the Swedish luxury brand, according to a report by Reuters.

"We're closing down Saab," GM Chairman Ed Whitacre told reporters on the sidelines of the Detroit auto show. "We're winding it down."

GM Vice Chairman Bob Lutz said that the U.S. automaker would press ahead with closing down Saab unless a new bid emerged that was "financially better for us than the wind-down."

"The offers we've received so far in terms of risk and financing up-front just have not been as good as winding it down," Lutz told reporters.

Dutch luxury carmaker Spyker last week said it had submitted an improved bid for Saab.
