GMC Sierra SLE 2013 Used Automatic Gasoline mileage: 300 KM or more 4WD GMC Sierra 2013, mileage over 400. I've had it since its model year until now. The oil strainer was repaired and replaced with a Denali strainer, and only one lifter in the engine. The car is in excellent condition regarding the engine, its power is strong and solid. The body has a dent the size of a palm behind the rear passenger tire, and some minor paint touch-ups due to fading. I am interested in trading for a chassis from 2009 and below. The last offer was 42,000.
