GMC SLT 2010 Used Automatic Gasoline mileage: 300 KM or more GMC Acadia 2010, clean, full option. The car has been used for four years, and I have traveled with it to Mecca and Medina more than once. I have overhauled the car from the engine mounts, top and bottom. It only needs steering rack repair, and everything else is fixed. Inspection is the best proof. The highest offer is 13,000, and the asking price is 16,000.
