GMC Sierra 2014 Used Automatic Gasoline mileage: 300 KM or more GMC Sierra 2014, half-full, double drive. The engines are guaranteed, the machine, the double drive, the gearbox has a slight jerk from under 100, it's in its original condition, I haven't disassembled anything, it's been there since it reached 100,000 miles. The body is factory guaranteed from bumper to bumper. Everything in the car is factory. New battery installed, new oils changed. It has additions (a fishing rod holder, side lights, shock absorbers, and a new BTM kit installed 10 days ago without any issues). The car is factory, no modifications have been made. I am the second owner since the factory. I have a brief report.
