I took my ZTT in for an oil change and I sat and watched the dudes to make sure everything was ok, and I saw them looking around in the car. Then I saw them take a book out to look at something. while they were lookin somehthing up I asked them what they were lookin for..... Then one told me that they were looking for the washer fluid resivor and that is when I totally freaked! They didnt even know where that was and they were "NISSAN mechanics!" So you never know what you might get at any place including Dealers...........peace
