GM board decides to keep European Opel unit By Associated Press/ BostonHerald.com Tuesday, November 3, 2009 DETROIT — General Motors Co. says its board of directors has decided to keep its European Opel unit rather than sell a 55 percent stake to Canadian auto parts maker Magna International.            The decision came today at a daylong meeting in Detroit, ending a year of uncertainty for the troubled Opel brand and its English sister, Vauxhall.            CEO Fritz Henderson says in a statement that GM will present its restructuring plan for Opel to the German government soon. The move came even though Opel’s unions on Tuesday reached agreement with Magna for $390 million a year in cost cuts. ( © Copyright 2009 Associated Press. All rights reserved.
