Z71 2025 Automatic Gasoline mileage: 15 KM 4WD Peace be upon you, folks. I have a 2025 black Trail Boss. It has 15,000 miles. It's like new, I haven't changed anything on it, no modifications or anything else. I put 3M PPF on it, tint, and installed a bed liner and side steps. I bought the car from the dealerships. It has a distinctive plate: S Q R 2 8 2
