just sold my car!! need advice
 

Finally sold my car today for a good price, and I'm ready to start the ball rolling on my 8. I want a Ti Gray with GT red/black possibly nav if the price is right. I'm gonna get a few dealers in the southeast to battle it out. I know Trussville in Alabama is selling at cost, who else is, particularly in Florida?

I need to know what a good place to start negiotating the price is, and how low I can get them to go. I've never bought a car myself before, help!!!

FYI - my best offer thus far is from Lindell in St. Pete at $400 over invoice, but they don't have the color I want. Fairbanks here in Orlando said they can beat what I can bring to them, and they have the colorI want.

now on to the financing part...
