I've been scoping 350Z's since they've arrived at the dealerships. Today, all of them go for MSRP. (leases/purchases) There is a website I'm sure you've heard of called
www. edmunds.com - they provide what is called TMV (True Market Value), surveying Nissan dealerships/buyers from all over the US to provide user's with what the average sale prices are on 350Zs. Dealer's regonize this and will adhere to them.
