GMC Sierra دينالي 2007 Automatic Gasoline mileage: 282 KM 4WD For sale, Sierra 6 liter 8 cylinder. The car, in short, is a sheikh and has no issues. I just finished its complete renewal from bumper to bumper. If the inspection reveals anything, I will bear it. It has a 3-inch muffler and outlets, a filter with a gear cooler. 40 thousand. The car, in short, is very good. Mileage 280 thousand. The double is disconnected.
