It is worth fixing up? Absolutely but do not spend one cent that you don't have to. Test build the bike. In other words, get it ready for the road and try riding it. Don't waste a lot of time or money making it cosmetically perfect. Just get it into safe running condition and then, if it is a decent fit for you body size, ride it around for a week or two - perhaps even for the rest of the riding season.

With the bike test built and ridden, you will be in a better position to decide if it is worth your time, effort and cash to restore/refurbish. My guess is that you will like the bicycle and the way that it rides unless you start comparing ride to higher end machines.

And as for value, who cares at this point? It will be worth more complete and running. In closing, I agree with some of the comments voiced by others regarding value - $100.00 to $200.00. But that is just a guess. Final value depends entirely on the person who wants to buy the bike and I have sold newer Peugeot UO8 mounts, like this blue one, for over three hundred dollars.
