GMC Sierra 2013 Used Automatic Gasoline mileage: 300 KM or more Peace be upon you. I am offering you a GMC Sierra. Model: 2013 Color: Black The rear left door has been replaced without any bodywork. The edge of the rear left door. The car's body has a dent near the gas cap, which has been repaired and painted. The transmission has been overhauled, not due to a malfunction, but rather because the previous owner did not change the transmission fluid, and changing it by me led to its overhaul.
