GMC Sierra 2014 Used Automatic Gasoline mileage: 300 KM or more GMC Sierra 2014, half-full, double. Engines are guaranteed, the engine, double, and gearbox have a slight jerk below 100. It's been like that since I got it, I haven't fixed anything. It has 100,000 miles. Body is factory guaranteed from bumper to bumper. Everything on the car is factory. New battery installed, new oils changed. Added (a fishing rod holder, side light, shock absorbers, and a BTM kit installed 10 days ago, without any issues). The car is factory, no modifications. I am the second owner since it was bought from the factory. I have a brief report. Gentlemen, the car has been offered for (60,000). There is room for more. Contact me if you have a better offer.
