According to Automotive News, recent comments from GM Vice Chairman Bob Lutz indicate that after putting Saab under "strategic review", no potential buyers have surfaced. GM has been privately looking for buyers for Saab as the company looks to shed all but its core brands.
One potential option for Saab is to take money from the Swedish government, which said in December that they would make 25 billion kronor (equivalent to $3.19 billion) available to Saab and Ford's Volvo division as a loan. The folks in charge of Saab have yet to decide if they will take the Swedes up on the offer but given Saab's nearly 35% decline in sales year over year, I'm betting they do.
It's sad to see Saab in the past decade only shifting from mechanical problems to financial problems.
