congrats, we're still waiting for ours to come in.
i've bought a couple of new cars, and all you really need to do is walk around the car and make sure nothing is out of the ordinary. make sure there are no scratches, dings, nicks, no equipment on the car that you didn't want on it, nothing missing that you DID want on it, etc. and, dont take delivery if you are not 100% satisfied with it. its a big purchase, and they should make you feel all warm and fuzzy when you drive it away.
