GMC Sierra 2010 Automatic Gasoline mileage: 300 KM or more I bought it without inspection and it had an engine, gearbox, and differential issues. I changed the engine to a 6-liter iron, a genuine differential, and fixed the gearbox. I installed a 40,000 BTU cooler. All of them have not driven 20,000 km. Chassis is sound. Body airbags deployed. Scattered paint jobs. What does it need? I forgot to change the engine seals after installation. The front ones need changing approximately. Gearbox mount + 4WD is canceled and available for whoever wants to reinstall it, and it's guaranteed. Do not complete the payment until you install and confirm. Full paint job due to fading in some areas. Interior polishing. Selling to the highest bidder. Oil is changed every 3000 km. I care about its engines, but the body, complaints are to God.
