Same as Stew, I had mixed feedback. First dealer I went to see couldnt care less, so they got nothing from me, other than a joyride in their demo. Second dealer was much better, agreed that I couldnt take calls at work so would email me. Always emailed me back within an hour or so and they then got all my servicing on the 350z and also made the sale on my 370z, so for a few emails, they have made quite a lot of money.
Generally they just seem disinterested. I think they are so used to selling Micras to old biddies that just rock up and pay ticket price that they arnent interested in spending a bit of effort to sell a Zed worth about the same (second hand 350z vs brand new Micra), where a buyer clearly knows more than them.
