Compare "for sale" units comparable to the one you're interested in and do a nationwide search to see all the possible options out there. I do this everytime I purchase a car just so I'm as informed as possible on what this model/year is being offered for sale. When I bought my used C, it was the lowest priced 28' on the internet, however, I had to drive 3 states away to inspect it and still offered $6500 less than what I already knew was a "good price". We were prepared to drive back home and the seller knew it. After the normal back-and-forth, I still was able to get $1,500 more dropped off a very good list price. I, for one, enjoy the art of a good negotiation. The key is being completely informed and understanding the principle of substitution (paying no more for an item that can be readily found at a lower price).
