GMC Sierra 2011 Automatic Gasoline mileage: 285 KM Peace be upon you, 8 cylinders without double, the muscles are excellent. Sierra 2011, gearbox, engine are clean, chassis and differential are guaranteed, and the mileage is 286, subject to increase. The car, God willing, is solid, and the interior is clean, and the exterior is clean. The body, by God, I don't know about it. I got it a year ago and only inspected the engine and gearbox. There was a minor accident that did not reach the radiator, and a screen was installed, and very strong lights were installed. The car is guaranteed, and the body, I think, is original. The car was used by my father, and I guarantee that it has never been modified. The sale is not urgent.
