LTZ 2003 Automatic Gasoline mileage: 300 KM or more 4WD Peace be upon you. I am offering for sale a Chevrolet Avalanche 2003, full option, American. Registration has expired. Inspection has expired. Mileage is a little over 300. There is an accident shown in the picture on the right side. The accelerator pedal is not responding, they tell me it's a sensor, but the rest is working.
