There may be hope still for Swedish car maker Saab. After declaring in mid-December that the brand would be shut down, owner General Motors said it will drop the year-end deadline for bidders hoping to buy the company. Last month, the Swedish supercar maker Koenigsegg withdrew its bid to takeover Saab after financing fell through. Recently, Spyker, a Dutch sports car maker, has expressed interest in buying the money-losing brand, which employs 3,400 workers. GM may also restart Saab production lines in January to start building the company’s newest car, the 9-5 model.
