The SAAB logo is seen on a car in Schaumburg, Illinois, November 24, 2009. A deal for General Motors Co to sell its Saab brand collapsed on Tuesday when the buyer pulled out in a move that threatens the Swedish luxury brand with closure. GM had been aiming to close a deal by the end of next month to sell Saab to a partnership led by the Swedish luxury car builder Koenigsegg and backed by China's Beijing Automotive Industrial Holding Ltd.
