GM's Third Quarter Sales Results

GM's sales are doing better this year than last. Call me crazy but how is this possible? They are facing all sorts of situations that aren't necessarily positive. Talk about combining the good with the bad. Announcing that sales went up 121% in September 2008 compared to September 2007 sounds way off. I know I'm coming off rather relatively rash right now but all this just doesn't make sense to me as of yet....
