Went to Faulkner Mazda.
I got 8% off sticker price with some minor negotiating.
I felt the most comfortable at this dealership. No hidden agenda, no upselling, and no other bs to get you in the door. So I just decided to get it from here.
This was without any type of incentives or rebates (I didn't quality for any).
I possibly could have haggled some more off, but this was around the time when the turbo models were pretty new on the lots and when dealerships just started getting inventory on the lots. I remember at this time, the GTR and Sig's were selling as soon as they hit the lots. They didn't last.
Plus, i was sick of negotiating with dealerships in NJ/NY and just didn't feel like haggling anymore.
8 months later now, and you definitely should be able to do better.
