GMC Yukon SLT 2018 Used Automatic Gasoline mileage: 414 KM or more GMC Yukon XL 2018 very clean for the user, no complaints. I am the second owner and have maintained its services regularly. The gearbox, engine, suspension, chassis, and airbags are all in good condition. There are two minor, very light paint repairs that do not affect the user. It was offered for 48, and the selling price is 55 for a serious buyer. Inspection and registration are both new. The car's mileage is 414,000 km, mostly highway miles. The car is in excellent condition, well-maintained, with no signs of heavy use, and the interior is very clean.
