Just thought I'd offer a few tips of advice. First off, you'll go much farther not making any comments about what the car is worth. They know what it's worth, so don't go into that conversation. Really hard to say how much they actually have in it.
Do you want the car? If you do, have an idea of what it's worth to you. Would suggest you find out about financing and such to where there aren't any surprises.
Haven't found a car dealer yet that isn't open to fair negotiations. Even though this is a nice car, it's only sellable to a small percentage of the population. With this knowledge, make an offer about 3grand less than the asking price they now have. Leave the personalities out of the negotiation. And if they don't want to dicker, leave! More than likely, they have about 5 grand less than trade-in value in the car. No dealership pays trade-in value anymore...
Hope this helps...
PS, make the experience with whatever Z you purchase an enjoyable one. By the way, mine is a base with the Sport package in the gunmetal gray metallic. Car looks very elegant while still being visually mean. I like not having all of the "fluff" on mine. Sport package includes the pieces I'd want if I was ordering one....
