I will only negotiate an "out-the-door" price.

I don't care what other numbers on the invoice for taxes, license, doc fees or any other junk fees are.
The only number that matters to me is the one I write on the check.
I write one check, you hand me the keys. Done.

At this point, either you have a deal, or you don't. If the deal is not final, you are still in the negotiating phase.
