GMC Sierra 2011 Automatic Gasoline mileage: 275 KM 4WD Peace, mercy, and blessings of God be upon you. I present to you a Sierra 2011.. it has driven 275,000 km. The car has been with me for approximately 9 years, and I have only seen good from it. The car's mileage is considered good.. I have taken care of it and its oils, changing them at the agency, Al-Jameel AC Delco. I just had the car fully repainted for a color refresh to make its appearance better. I installed new Bilstein front shocks. I installed new Shahin rims and tires. The body has not had any issues with me, praise be to God, but when I bought it, it had a right and left fender. The car has cost me and is ready for everything, even the bed has a liner installed. The sale price is 50,000 if it fetches that price, otherwise I will keep it with me.
