GMC Sierra Z71 2009 Automatic Gasoline mileage: 300 KM or more Peace be upon you. I am offering a GMC Sierra, original body except for the front right fender, which has some minor touch-ups and modifications. The oil pan was removed and the oil valve was changed. It has 406,000 km. The vehicle has been parked most of the time. 4 gears, no 4WD. It was appraised at Al-Qadisiyah showrooms for 25,000, and we hope for more from God.
