I'm not sure how this would work but I'm willing to trade my 2012 Silverado with 7" FTS lift, 35" tires, 20" rims (pictures on profile) with 5k miles for a 2011/2012 Duramax with reasonable miles. We would compare costs of vehicle and see where it stands and possibly add a cash value. Again not sure how this would work but I just would enjoy a diesel rather than gas. PM or respond with suggestions and/or offers.
