GMC Sierra Z71 2013 Used Automatic Gasoline mileage: 340 KM or more 4WD Sierra 2013, I accept exchange for Sierra 2014-2015 only and I will pay the difference. The GMC has no issues, its condition is very good, mileage is 340. There is a minor, unnoticeable dent on the rear fender and it has not been repaired. Also, there is paint on the passenger side fender, and the paint is only a small area. The rest is sound, engine, gearbox, and chassis are sound. Airbags are also sound and all are guaranteed. (The spoiler on it is for leaf spring suspension only) and it has not been modified since it was manufactured.
