That bike is much older than 10 years. Probably somewhere in the '80s
The bike pictured below is quite similar to yours, and was built in 1985.

Note however that these frames are generally of good quality, and if not terribly rusty can be used for many more years (and of course are very cool and retro looking).
These old racers still make for great touring/commuting bikes! (Not entirely unbiased as I have multiple bikes like this and love them a lot!)
The price of such a bike, given that the frame is OK, is mostly determined by the state of all other components (wheels, gears, seat etc.) By the looks of it, most of the stuff on your bike is original, and looks like it's in good shape (definitely check this for yourself, photos are deceiving).
If everything is ok, I would probably pay around 100 - 150 € for this. Don't be fooled because of the supposed retro-coolness, these bikes are quite abundant and not rare at all.
If everything is not ok, drop the price below 100€ and do some work yourself, very rewarding and fun!
