Its not a bad price, I think you may be able to work it a little lower but its a 2012 model and its 2011 so you won't have so much room to go below invoice if it was a 2011.
**STICKY** How much did you pay for your 370Z?**STICKY**
That will have some prices for Nismo's in it. for reference I got mine (2011 in March) for 37,700ish +taxes and fees. Though I understand the 2012s are a little more expensive.
