The dealership was Landmark Honda in Alexandria, VA. My negotiations consisted of sending emails to all the dealers in the area. In the email I made sure to tell them that I knew what the invoice price and holdback were and told them that the lowest price would win my business. Only like 3 dealers out of 9 emailed me back with a price, and that was the lowest. I went to the dealership, test drove the car, and then bought it. No haggling at all.
