Z71 2012 Automatic Gasoline mileage: 300 KM or more 4WD Peace be upon you, my brothers. I have my Sierra car, personal use for 5 years, I have not complained about it. The car's body is cosmetically sprayed, chassis is original, airbags are original. The car is clean, as you can see. 1 - The car's undercarriage has King springs and shocks, and the floor is polished. 2 - Engine and gearbox are guaranteed, God willing. 3 - All consumable parts have been replaced with original GM parts: radiators, engine mounts, hoses, and all maintenance and wiring insulation the car needs. 4 - Cat-back exhaust from Max Power worth 5000. In short, the car is for the user, not for the dealer. And whoever is serious, good luck to him. The car is located in Al-Ahsa.
