How would you guys value a 1985 Trek 620? Appears to be in good to very good condition, original components, factory rack, supposedly cleaned and lubed. It's a small frame, which is what I need. It would actually fit me or my son. I may not be able to see in person so it may be taking a chance. First price out of the gate is in the $500 area. I've been watching for a touring bike and ran across this one through another contact. Not very many bikes like this show up in the south. Thanks.
