I love the Denali! It drives more like a Mercedes M, but smoother. The fit and finish is amazing. The sound (or lack of it) is great! The MSRP on it with Nav, rear ent., sunroof and 20" wheels is $54,500. I paid approx $47,900 ($500 under invoice).
I have owned 5 foreign cars/trucks. 1 VW Jetta in my teens, two BMWs and 2 Range Rovers. My last BMW was just too small for my growing family so we decided on another SUV. We considered the X5, the Armada, the new ML, and the Navigator. After driving all, we were thoroughly impressed with the '07 Denali. To us, by far it was more luxurious than all the others, the ride quality is top of the line, it had ample interior space, and its exterior is quite impressive-and Yukon has an excellent reliability track record. We have black/cashmier, fully loaded with every single option. At least one person does a double take every day I drive it. To spend $50K and not have any remorse says it all.
We now have over 3,000 miles after 3 weeks and really enjoying the ride. Took a Trip from S. Louisiana to Atlanta and got 18.5 MPG even with the rains and traveling 70-75 mph. The 5.3 V8 with the 3.42 rear end helps with the economy.
At 19,000 miles (yes, 19,000) the transmission went completely out. GM did pay for the tow and fixed it quickly. It didn't cost us a penny since it was under the 100,000 powertrain warranty. Currently the vehicle has about 28,000 miles and the transmission has started slipping everytime I take off.
In addition, the driver side air conditioner blows out HOT when set on the coldest setting while the passenger side works fine so I have to close all the vents on the driver side and put the passenger side vents on me to get cool air. GM probably won't cover this since it's out of the bumper to bumper warranty. This is will probably be the last GM I buy.
Traded a nice 2002 Sierra for this fully loaded Yukon and what a step up this is. Only had it a couple of weeks and I'm still in awe of just how cool this big SUV is to drive. Took a while to find one with all the goodies without a sunroof (cuts down on head room). Besides, this is Texas. We get in our vehicles to get out of the sun. I'm hoping the gas mileage improves, but I didn't buy a full size SUV thinking it would get 30 MPG.
