Congrats on the purchase! You'll like the X. Get over the warranty issue, because if you decide you're going to go offroad, you'll find the mod bug biting you. Like everyone else, watch out for the trans radiator cooler and front diff. Those are going to be your weakest areas, but there are plenty of folks who have done the mods already and have posted the "how" on the forums already mentioned. I've had 2 X's and will keep my '04 forever. I use mine for offroad running and lots of vehicle camping as well. Of course my wife isn't sure who I'm married to, her or my X. Oh well, she'll figure it out one day.
