I contacted Triton back in the late summer for a list of C-Dory dealers. The list they sent me was pretty short. I would forward the list on to you but I can't find it now. If I remember correctly there were two listed on the east coast, one in Chesapeake Bay area, Mobile East Marine in Pamlico Co., NC (very nice and helpful people there), Wefings Marine on the Florida gulf coast (Mark was quite helpful and will bend over backwards to answer your questions), a couple in California, Sportcraft Marine in Portland, OR (where I ended up buying, ask for Tim), and one or two in the greater Seattle area.
With that said, in my searching I came across a few dealers advertising new C-Dorys that weren't on the dealer list. From the people I talked with I got the feeling that right now the "dealer network" pretty much consists of dealers willing to buy boats from Triton up front for resale rather than a "floor plan" situation like auto dealers have. The way the economy has been the last few years I can understand that.
As far as pricing a new boat I contacted dealers, told them what I wanted and got quotes. Then there was some back and forth with, "I don't want that option but I do want this one..." to get the final price. After a cross country road trip looking at used boats I ended up buying new from Sportcraft in Portland. Sportcraft actually sent me a price list to work with to give me an idea of what was available and a way to come up with a ball park figure of what it would cost me. When I decided exactly what I wanted they gave me a final price and were very good about discussing the different options. There were a couple of things I wanted that they ended up installing rather than ordering on the boat from the factory because it could be done cheaper that way.
Depending on what you want on the boat you can save money if you're willing to do some of those installations yourself if you're inclined to do that sort of work. Things like VHF radio, depth sounder, chart plotter, compass, fuel flow meters, additional lights, etc., don't cost so much to buy but are expensive for the dealer to install due to labor costs. If you're willing to do those and other installations yourself it can save you a lot on the purchase of a new boat.
