The sponsor of this site has two dealerships. One is 16550 West Dixie Hwy, North Miami Beach, Florida. The other one is in Ohio.
The Honda dealer in Chatanooga was also reputed to have some new old ones.
As a courtesey, call Hal first or second, but give him a shot at your business. He's a standup capitalist. (That's good in my book!)
West Honda in Rio Rancho NM (Outside Albuquerque) has been getting a few of those 03 1800's. I ride past them every day and they had a sign out the other day stating a $4000 discounts. Tenn might be closer to you though.
