JK, you can call Auburn Sports and Marine to get an estimate of the boat's worth both wholesale and retail - at least I assume it can be done on a boat that old. I called them when I sold my Starcraft for a blue book price. I can't remember the name of the guy who does it there, but they were real helpful.

I later found a web site by accident, which was right on with their estimate. I can't recall the website, but I was using google to get some boat info and it came up.
