GMC Sierra 2011 mileage: 37 KM For sale, Sierra. Engine is guaranteed, and the gearbox is guaranteed. The car is ماشاءالله (masha'Allah - what God has willed). I travel long and short distances with it and it doesn't complain about anything. No 4x4. Mileage is 367,000 km. The body is intact. There are pictures available, but only serious buyers should inquire. Good luck, God willing.
