2006 Automatic Gasoline mileage: 275 KM 4WD For sale: Red Hummer H3, model 2006. Its 3.7 5-cylinder engine is working perfectly with no issues. The transmission only engages in D at speeds of 60-80 km/h, shifting into fourth gear; other gears are working. The body and chassis are in good condition. There is some fading on the hood. It needs consumables replaced. Maintenance for the heavy-duty 4WD system, possibly programming or a dynamo, but the 4WD shaft is fine. The sunroof needs maintenance. New registration and inspection. Quick sale, and I won't disappoint the serious buyer.
