I've read all the threats (big thanks to Laura who posted links to a whole bunch in one particular thread) and am in the middle of it now but need some advice.

I'm waiting on the e-mail responses now. Got two quotes already and they are basically at the invoice cost, but am still waiting for 3 more.

To simplify things, I just made a connection that can help me. I happen to know the wife of the president of a car-dealership corporation through work. She told me to get in touch with the general manager of this particular dealership and tell him that she referred me to him. Obviously, once I go and meet w/ him, he needs to make sure I walk out w/ a car since it would look so bad for him. So how low can I go w/o being insulting? We are also most likely going to lease so what else is negotiable?

Oh, we are looking to get an Odyssey, btw.
