I apologize for the words that were said before this thread got edited..
I checked in CA, and there arent many Nismos for under $30k.. Most were 35-40k still.
You can save a few thousand by flying out to Phx and picking up a 370z and driving it home. Taxes are cheaper, and car prices are cheaper then CA.
I have personally went and checked out this car. The lambo doors and underglow is a little much, but this one has 12k for $32k, but you can talk it down a couple thousand.

There are a couple more out there around 30k.. If you are interested, look online when you are ready and I can always drive and check it out, take pics for you, etc.. if its close to me. That way you know that you are buying a perfect car.
Just a thought! Good luck!
