Do you mind posting pictures? That would be most ideal. I found my friend the same bike in great/near mint condition ($140 parked right outside a bike store!), and I've seen some on eBay recently asking for $6-700 (although I'm not sure it sold). It's a quality build with a solid history behind it. From what I've read it's the lesser of the famous Trek tourers but I love it. Hard to say without pictures but if it looks like crap and I think I can bring it back to life mechanically... I'd say...$300 to start and maybe sell it for $250? I will definitely be checking back on this thread... =)
LA area prices tend to be higher.
