GMC Sierra Z71 2015 Automatic Gasoline mileage: 300 KM or more Peace, mercy, and blessings of God be upon you. I am offering my car, which I have offered before in a previous advertisement. The highest bid reached 58,000 from a serious buyer, and we ask God for more... .... Mashallah Tabarak Allah.... GMC Sierra, fully loaded, screen, lane assist, sensors, vibration alert for the driver's seat, and the known full options for the mocha color, specifically brown. Added a 40,000 BTU transmission cooler. Also, I have done comprehensive maintenance: oils, tires, spark plugs, spark plug wires, brake pads, undercarriage rustproofing, control arms, ball joints, axles, which cost a significant amount. Mileage is 370,000 km, subject to increase. Inspected and renewed. Transmission, engine, chassis, body are all subject to inspection.
