GMC Sierra SLT 2002 Used Automatic Gasoline mileage: 300 KM or more GMC 2002 Good engines and no complaints, praise be to God. Modified front end to 2006. I travel near and far. New tires, the car's undercarriage has been completely overhauled. The body was fully painted by its first owner. And you are safe. Only serious buyers should call, and offers should be made publicly.
