Z71 2011 Automatic Gasoline mileage: 300 KM or more 4WD I present to you a Sierra model 2011. The body is original from bumper to bumper, and without any paint. The engine was overhauled two months ago by a specialist, costing me a high amount, and its condition is excellent. The transmission currently has some issues and I expect it needs an overhaul. All its suspension components are excellent, the undercarriage has been fully repaired and needs nothing at all. The car is excellent, praise be to God. The reason for selling is that I want to buy a sedan. The car has never been modified at all. I am the second owner since it left the dealership. The car's mileage is 687,000. The car is for auction.
