Look under the hood and see if there is a sticker thats says if the 60,000 maintance has been done. (most done @ a Nissan service shop will have it) If not that is something you will want to have done and I think its $500.00 for the parts at CZP and what ever your local auto shop charges for labor (full 60,000 service) When I was looking for mine 6 years ago I found Z's in all conditions. Look at more then just one, after you look at several you will have more info from what you have seen to make your decission. Good luck! and welcome to TT.net
