I traded in my 8 year old Trailblazer on a 2011 Yukon Denali. I'm hoping to get the same result with the Denali as having 0 problems in the future. Good to hope anyway. The Suv drives real smooth on the road and is fun to drive. Size works fine in the garage and the wife has no problems driving. Rear view camera and nav are a welcome addition. no real negative comments as after 500 miles I have zero buyers remorse.
The '11 Yuke does just about everything better than our '06 did. The ride is smoother, the seats more comfortable, and GM has finally caught up to the competition in terms of refinement and the usefulness of the electronic gadgetry. The stereo and nav system are very solid, and the iPod integration via the USB port is killer. It also looks gorgeous (esp. in the RJT color)...we began receiving parking lot compliments the first place we parked it, and that continues. You don't buy this vehicle for the gas mileage; you buy it because you want it for what it is...the most capable true full-size SUV on the road. Towing, cargo, passenger comfort - the Yukon has it all.
Not a bad ride for an SUV. Handles like a car with good front end responsiveness. The interior is very well finished. Exterior is a cross between the Tahoe and Escalade which make it just right for some buyers. Fuel economy may not be appealing but most SUVs aren't bought for fuel economy. The Hybrid version should would be a good option.
