I agree with those that said to negotiate over phone/email before you go to look at the car. Cars are seductive and none are more seductive than a Porsche Boxster in the springtime.

Once you get them to agree on a price, have them email/fax you the "out the door" price which includes all the documentation fees, prep fees, etc. they expect you to pay. This is how I bought my boxster and it's a good technique to use if you and the dealer are far apart in the negotiation. And as someone said earlier, it's a lot easier to say "No" when you haven't traveled a long distance to buy your dream car.
