Z71 2013 Automatic Gasoline mileage: 300 KM or more 4WD Sierra 2013 full option, 5.3 engine / 6 gears. Mileage 400k. First owner. The car has no issues. Gear, engine, chassis are guaranteed. The lifters were hit and I replaced the original GM lifter set. The body has scratches on two fenders, they were repaired and painted. I change its oil every 5,000 km with Castrol 10w40 oil. It has been modified with a throttle body spacer, cold air intake, and a tune. It has Taiwan headers. It has American gas shocks. I don't have a set price. May God provide for us and you and decree what is best.
