Paper Tiger

I've talked with two dealers.

First dealer offered me around $33,000 and claim this to be only $1,200 over invoice.
Second dealer offered me around $32,000, but this is without the Aerodynamics package.
These prices are their first offers, I know I can do better than this price.

I was under the impression that $30,500 was the invoice price of a 350Z Touring, including destination & handling charge at $500 and added options at around $1,500 MSRP. The final price comes to $31,500. The first dealer claimed $1,200 over invoice, so it'll be $32,700, which sounds about right...
Are my calculations accurate?
Do you guys think I can do around $32,000 or better?

I have one more question, can I receive invoice price for the options as well? I'm sure if the MSRP for the total option I've configured comes to $1,500, the invoice price will be around $1,000.

What's your take on this whole matter?
