Price Check 2009 370z base w/Sport Package

[Grindkiezer]

This is my first post and I have been looking for a thread that I could just comment on and ask my question, but I haven't exactly found any luck with that. So instead I'll just post my question here and hope that someone could help me out or give me some advice.

So I am looking at a 2009 370z base with Sports Package m/t with about 30,000 miles on it. (This car is being sold from an Infinity dealership) So one of the salesmen here told me that the car started out at a little over $27,000 which I thought was a little high because I had been doing some research online before then and had seen some with less miles for about the same price or even a little cheaper. So after going back and forth with the dealership over the phone and though email, I managed to get the price down to about $24,500 which I thought was a pretty good deal . But I am just wondering if this is about as good as it's gonna get or if I'm completely off with my numbers.

Thank you in advance.
