GMC Sierra 2010 Used Automatic Gasoline mileage: 300 KM or more 4WD Excellent and solid GMC Sierra. I changed the transfer case and the gearbox, and both are still under warranty. The car is like a sheikh. It's capable, the interior is very clean, the airbags are deployed. The body, I swear to God, I bought it without inspecting the body. Everything in it is capable! The highest offer so far is 23 from someone who saw and inspected the car. The car's mileage is 547. The asking price for the serious buyer is 24.
