Low Mileage, Beautiful Condition, Always Garaged, Meticulously Maintained and Priced to Sell. This 2006 Yukon XL Denali is clean inside and out, with no known mechanical problems. On board DVD Player and excellent sound system, factory slide-bar trailer towing package, never used for trailer, ride leveling suspension, Seats 7. This vehicle is great for family trips, but our kids are all grown and in their 20's and we simply don't need this extra vehicle.
