The denali ultimate is the same price but does not have the luxury touches, ambience, and seat comfort of the navigator. Yes it has air ride, and some tech that the escalade has, but it will not have the luxury feel of a navigator. Also, though I am as annoyed as everyone there was no air suspension option, the truck isn't even out yet and everyone is already making judgements on The ride quality. Ford has made changes to the suspension, and they say it rides way better so let's wait for that. A lot of people, myself included actually think the current gen expy and nav rides better than the gms on most most roads, it's the rough road ride that needs work.
I will agree that the wagoneer feels fresher, but I wouldn't say better built and the quality is a lot less. The gw series 2 I drove had a lot of hanging trim and exposed wires. And the base revel in our nav (and 30 spkr unit) was way better of s stereo than the wagoneer 23 spkr Macintosh. My dads escalades 20 spkr unit was also better.
