GMC Sierra 2013 Automatic Gasoline mileage: 221 KM I am offering a Sierra model 2013. The car has been repainted and has more than one accident. The engine, gearbox, and chassis are guaranteed. Just drive it. I recently changed its oils and replaced the differential due to the crown wheel. The engine is 4.8. The car has no issues at all. Start it and trust in God. The sale is for the highest offer.
