I had this problem buying a motorcycle; I don't know if or how the local dealers coordinated, but I got a dramatically better price half a state away. I took the quote to the local dealer and offered to add on half what shipping would cost me. - worked out somewhat lower than any of the local dealers were willing to pay and I got to buy from a local dealer (which ended up not being a big deal anyhow, but it was something I thought would be important)
