GMC Sierra 2008 Automatic Gasoline mileage: 283 KM Peace be upon you. GMC Sierra single cab, model 2008. I honestly don't know exactly what's wrong with the car, but I just had it inspected, and the inspection papers are in the last pictures. The body has dents, which are further clarified in the inspection papers. I received an offer of 27,000, and we ask God for more. Please contact me if you are serious. Don't waste time. Everything is shown in the pictures. And may God bless you all.
