GM sub say bari automobile company hai agar wo apne badge k sath sale karen gay to on ko zada profit ho ga
They have a very Incompetent CFO in their HQs that is why don't worry about profit. Profit is faaaaaaaaaaaar away from GM's results. Just losses and that too very huge. 
GM is the largest company (lets wait for this years sales results) but that doesn't mean that it marks success everywhere. So they can re-badge the car if they feel that a particular brand will sell more vehicle in a market than with Chevy badge... (e.g. Toyota Cavalier in Japan etc.)
