GMC Yukon XL 2009 Automatic Gasoline mileage: 300 KM or more In the name of Allah, the Most Gracious, the Most Merciful. I am offering a GMC Yukon XL, model 2009. The car has 432,000 km, which is subject to increase. It suffers from a problem with the gearbox in shifting. The differential needs to be changed. There is a very slight oil leak. The chassis is sound. There are more than one impact, and we will clarify them. The serious buyer offered 12,000 and my asking price is 18,000, and we ask God for more.
