General Motors' Swedish unit Saab Automobile said on Thursday a group of Sweden-based investors had shown interest in the company. “I cannot disclose who they are. But I can confirm that there is a group of investors in Sweden which has shown interest,” Saab spokesman Eric Geers told Reuters. Geers said the loss-making carmaker, whose US parent has said it will sever ties to the brand, was being courted by six to eight “very large” companies in total. Earlier on Thursday Saab said it had given 750 employees at its Trollhattan plant notice of redundancy.
