SLE 2011 Used Automatic Gasoline mileage: 1 KM 4WD Peace be upon you. I am offering a Sierra, model 2011. The car has a project on it. It has a full cam package from BTR. It has performance lifters. It has a MELLING pump. And it has full air intakes. KN intake. Corsa replica muffler. And it has a 40,000 BTU transmission cooler. And the differential has been modified for performance. The car has 450,000 mileage. As for the body, I have no information about it, but it is neat. There is a small hit on the front crossmember, as you can see in the picture, and it does not affect the car. It was offered for 37,000, and the sale is near.
