This is my 6th Duramax (and still have the 5th) and I love the new interior design with Nav and DVD players. Sunroof definitely better too. My only complaint is the new emmissions equipment really chokes this thing and kills mileage; I get 14 in town and 18 highway with some modifications. For those wanting a better ride, try a front leveling kit with longer shocks; it helps tremendously. Also try a cold air intake and bigger exhaust; helped my mileage alot.
