This is by far one of the best vehicles I have owned. Traded in a 2010 Mercedes E350, loved that car but it does not even compare to the Denali. We looked at Suburban and they are beautiful as well but wanted a little more. Drove a Escalade ESV and loved it but just cannot see where there is a need for a extra $10-12k. So we went with the Denali and haven't looked back.
Rear entretainment and all the room, classy look. Pretty much love everything about it.
I really don't understand the need for the 6.2 and AWD. I think it would be fine as a option but dont really see the point unless you really need it and I would say 90% of buyers do not. Wish you had the option of 5.3 with a selector for 2wd and 4wd. Fuel mileage could be better but for the size and what it is I think it is doing great. We are averaging 17-18 local. Would be awesome to have the same nav screen as the Escalade.
