GMC Yukon SLT 2009 Automatic Gasoline mileage: 280 KM 4WD Peace, mercy, and blessings of God be upon you. I present to you a 2009 GMC Yukon, a car in excellent condition, ماشاءالله. Start it and travel, no issues. The car is government-owned, used personally. I travel a lot with it, ماشاءالله, but it needs polishing and all oils are new.
