Additional Dealer Profit, or ADP, is a tactic used by many dealers to start negotiations at a higher price—so they can offer you a "discount" without losing any profit. Dealers will try to negotiate down from the ADP. You, on the other hand, want to negotiate up from the dealer cost.

Ingnore the ADP

So what do ou do about the ADP? Ignore it. You are not obligated to pay this price nor—most likely— should you if you expect to get the best deal possible.

When used, the ADP is usually posted next to the MSRP sticker on the car.
