Buying soon, need advice.

[nick_danger]

I will soon be joining the ranks of the 300C owners by purchasing a 2006 300C... perhaps even a new 2005 if I can find one. I'm working with the auto-buying service at my bank and they quoted me a fully loaded 300C, but I guess I would like some very specific advice on how to handle the delivery of my car. I'm in Minnesota and I'm curious as to warranty items, rebates, or other details I should know about to ensure I get absolutely everything I need to make this purchase one for the history books.

What are often overlooked items that should be included with a 300C purchase? (manuals, mudflaps, floormats?)

What warranty (regular or extended) options are there? How much? I hear a lot of people talk about free oil changes for a year, roadside assist, etc. How much to move the 3/36 to a 7/70 (assuming I get a 2006 over 2005)?

What is the lingo? What are the codes and such that I can feed the dealers to make sure I get the exact items/services I should?

Thanks in advance!
