My main concern is the type of leather they use in the rear seats in seating area. The SLT model had the rear seat made out of vinyl rather than real leather. This is pretty sad since my 2004 GMT800 Yukon had real leather in the backseats.
Now, since I'm planning on the 2017 Yukon Denali, I'm wondering whither the rear seats upholstery are made of real leather or not?
