Hummer H3 2007 Automatic Gasoline mileage: 1 KM For sale, a Hummer H3, a gem for the user. AC is like ice ❄ In very good condition, all parts have been replaced, and there are new parts that haven't been installed yet, costing me over 10,000. There are some minor issues, which I will mention to the serious buyer. The car is great for long trips and beautiful on the road. It's mostly parked due to work. Mileage is over 300, and the odometer has been stuck since I bought it, I don't know what the problem is.
