General Motors agreed last night to sell its Saab Automobile brand to the Dutch car maker Spyker for $400 million. Spyker, which manufactures luxury sports cars, will form a new companyÔÇöSaab Spyker AutomobilesÔÇöto take over the brand. The Zeewold, Netherlands-based company employs 110 people and produces between 30 and 50 cars per year, which each sell for around $200,000. Saab, which currently employs 3,400 workers, last year manufactured 24,000 cars. Spyker is estimating that it will make 100,000 Saabs a year, enough to be profitable.
