New ones retail for $589 base price, and go up from there, depending on options. The main thing that has changed on these, over the years, is the fork. Being that this is a current-production bike, it´s kinda hard for sellers to try to get premium prices for a roached&rusty vintage one....
Either way, it´ll be fun to toss up some pics and let us know what the guy is asking. FWIW, I bought a used one, a few years old, with dented fenders, typical bad Worksman paint, and no basket for i think $150 off of craigslist. I might have held out and gotten one for less, but the truth is, these things don´t pop up often....
