the Z at the end. All LTZ does is give you the little options standard that would be an option on an LT, like power fold seats, rain sense windshield wipers, power lift gate, and some other stuff. Nav and dvd are options on all of them, i think the only option you cant get on anything but an LTZ is the power running boards. other than that its just the Z at the end.
cool...Thanks!:thumbsup:
