GMC Sierra 2016 Used Automatic Gasoline mileage: 211 KM 4WD 2015 Sierra converted to 16, full option front end. 1. 40k BTU transmission cooler. 2. Has a BTM cat-back and Y-pipe. 3. Tuned to remove the disconnect, the 4-cylinder system is canceled, throttle response, and tire size adjusted for the transmission. 4. I just did a full service with a new original radiator, thermostat, and elbow, and changed the hot AC lines. New original GM control arms. It has sports control arms and front shocks, and springs. I don't know the brand from the previous owner. It had spacers and I removed them. 5. Engine: lifters changed by the previous owner. Original transmission. Oil changed every 50k. The car has 200k+ miles. Thank God I haven't had any complaints since I bought it. Original parts are available. Plus, the car has a 16 front end conversion and front chassis, but no damage. Its condition is good, and you have the right to test the car.
