Chevrolet Tahoe LTZ 2011 Automatic Gasoline mileage: 1 KM 4WD Peace be upon you. GMC Tahoe, everything is guaranteed and I will mention what's wrong with it. The body has scattered paint jobs to protect against fading. The 4WD is disconnected and only needs a 4WD differential. Transmission, engine, chassis, and suspension are guaranteed. Full option, electric trunk.
