I have owned just about every luxury SUV auto available, including Mercedes, and the GMC Yukon Denali is far and away the best SUV vehicle I have driven. The quality gets better every year it seems too, despite a high level each year. My only "wish" would be that it would have selectable AWD vs. 2Wheel drive.
We looked at Escalades, Navigators, Excursions, Expeditions, Tahoes, etc. but really liked the Yukon Denali the best overall.Excellent horsepower, fair fuel milege, very comfortable seating for a family of 4 and gear. If you have the need for more than four then you better get the XL or you will be disappointed.
Wow...too many things to talk about. The stock horsepower could be termed sporty -- almost as good as my Jeep with the V8. Interior creature comfort and gadgets (Nav/sun roof/DVD player).
GM knobs are so cheap looking when compared to other makes. Also, take a lesson from Ford in fold down seats. This vehicle costs too much to have to manually remove 3rd row seating and cheap plastic controls.
