GMC Yukon دينالي 2012 Automatic Gasoline mileage: 300 KM or more 4WD Peace be upon you. The car has 390,000 km. And it doesn't need anything. The transmission was overhauled due to oil mixing between the engine and the transmission. And since I overhauled it, it hasn't had any issues. The engine had its lifters replaced due to a manufacturing defect. It was offered for 23,000, and the sale is near.
