GMC Sierra SLE 2020 Used Automatic Gasoline mileage: 75 KM 4WD GMC Sierra 2020 Standard 8 Cylinder Double The car's mileage is 75, can be increased. I personally worked on the car, I bought it from a second owner, it was nothing. The car has a Max Power kit, a Bullet intake, a Volant filter, a bed cover, original tire covers, a transmission cooler, an alternator isolator, a siren light isolator, and two outlets, and there is an extra outlet besides the factory kit. It has tinted windows, a chip tune and programming, Profender 2-inch shocks, front and rear King springs, and Oxide control arms. Mashallah Tabarak Allah. Mashallah Mashallah Notes There is a slight dent in the rear bumper, it doesn't harm at all, it's shown in the picture. Inspection papers were with me when I bought it, and inspection papers from the previous owner are available.
