GMC Sierra SLE 2021 Automatic Gasoline mileage: 105 KM 4WD For sale, Sierra 21. Body and engine are original, except for a paint spray on the rear left corner the size of a palm and a barely visible dent on the rear right. I mentioned them for full disclosure. The car is good and excellent, with significant added modifications: - New custom Bullet kit - Bed cover - Hisham programming - Sports filter - Installed sway bar and ABS links - Side light - New Profender gas control arms and shocks, under warranty - New Kuwaiti rims with new Maxxis Abu Jamal desert tires - Full tune-up for the car - Trucool 40,000 BTU transmission cooler - Transmission oil change In short, the car is excellent, capable, and worth it. I use Liqui Moly, one of the most expensive and best oils.
