I researched and drove and five different SUV's prior to purchasing the Denali. I am real estate and it helps to sit up high to look at property. The vehicle is nicely appointed and comfortable. Plenty of pick-up for merging and passing on the highway. The captain chairs in the middle row sealed the deal for me. My business partner is 6-8' and fits comfortably in the middle seat. I would recommend this vehicle to prospective purchaser. Only problem I have had is with the exterior door handles and the dealership replaced them at no cost. Definitely worth paying a little more compared to Tahoe/Yukon.
Seats, captain chairs, DVD player and horsepower.
Electronics could be sexier but it is a truck at heart.
