If/when you try to sell the bike make sure to put in the ad that you're the original owner. If you happen to have a sales receipt or anything like that you could get more money for the bike just from the coolness factor of being the original owner.

It's a beautiful bike, I agree that the right buyer may pay $300-$400. It's a limited market though. I don't think there are tons of people searching for your bike like there are for Paramounts, etc. Ebay might net you quite a bit more money than craigslist for this one.
