Questions about owning an H2

Hello everyone, Just registered on this board and visited it yesturday in search of some general info. As you can tell by my user name I am a Ford owner by birth. My wife has really taken to the idea of getting a H2 and I want to make her a happy camper (as a husband should want to do in the first place). We have been to the local Hummer dealer a few times in the last several months and I/we have a few questions about owning a H2. She wants to get a used one from an 03' on up and I am pushing for a new one to get the warrenty and know where the truck has been from the start. She wants the LUX package on the truck with most of the bells and whistles and I don't care one way or the other as long as she is happy with it. Now I have been reading and trying to find as much info on these trucks as best as I can but I figured where else to get the best info than from the current owners. So is there anything that we should look out for on a used H2 that anyone has run into. (I read most of the cracked diff thread and will look at that if we decide on a used one). From the test drive we took last week (granted I sat in the second row behind the wife and salesman) the ride was nice and quiet and the truck felt open with plenty of room inside. Just wondering if anyone has had problems with the seemingly complex drivers setup. We both decided against the Navagation system and what the CD changer and the kids want seperate video in the rear section. Hopefully some of you can chime in and I can get some real world input as to which way to go with this purchase. Thanks in advance.
