GMC Yukon SLT 2019 Automatic Gasoline mileage: 59 KM I am offering a 2019 GMC Yukon. I bought it from an old man and it has been with me for less than two weeks. It has 60,000 km. It was offered for 160,000 and I haven't completed it. The limit is 170,000 and I am firm on that, we will not disagree with him. Please do not undervalue the item and only serious buyers should contact. Do not be stingy.
