I'm a loyal Chevrolet owner and have bought and owned over 25 new Chevys in the last 20 years for personal and business use. I recently bought a new 2013 Chevy Suburban that I am not happy with. It just deosn't have the towing power I need. It currently has 2200 miles, no damage and has been returned to the dealership. I want to replace it with a new 2013 Chevy Silverado with the Duramax. When I called Chevrolet to enquire as to how the program works I was told I took delivery 5 days before the program started and the vehicle could not be returned as part of the Buy Back Program. Can anyone give me some suggestions as to who to contact at Chevrolet to see what can be done?
