The biggest additions to the GMC Yukon SUV for 2005 came from new Stabilitrak and touch screen navigation.  Otherwise, GMC added a couple new exterior colors for your viewing pleasure.  This domestic vehicle comes in 5 trims: the SLE, SLE 4WD, SLT, SLT 4WD, and Denali AWD.  The Yukon offers a powerful set of V8 engines, including 4.8 L, 285 hp and 5.3 L, 295 hp models.   All trims have 4 doors and room for 8-9 passengers.  Gas mileage generally comes out to 15 mpg in the city and 20 on the highway.  The 2005 Yukon can tow nearly 8000 lbs. and gives you nearly 105 cubic feet of cargo space with the second row folded and the third row removed.
