Since you are trading in a car, youll be able to negotiate a little better then I was because I had nothing to trade in. The dealers will lower the price of the car they are selling to as low as they pretty much can, but to make sure they sell you the car they will work with giving you more money for you car than it is really worth! Just don't be too eager to get the car, call dealers around, possibly sign up for truecar.com and all the local dealers will call you up with their offers and negotiate from there. If you have a Costco membership check out costcoauto.com which they will do what truecar does, but they give you some sort of discount (like $500 under invoice) since you a Costco member. Just don't be in a hurry. If you do negotiate a deal over the phone, have them or the manager sign the offer they are willing to do on a new gti or used, and fax it to you. So when you go there you have proof of what they said.
