To be honest I had a look and it was quite battered so obviously I said no thanks for the advice :-)Equipment-wise it'll be old 10 speed, 105/Ultegra 53/39 would put it 2008-2011.
Whether it's worth that much will depend very much on condition: if it's hardly used then possibly. If new chainrings / chain / cassette / cables / etc. are needed then no. Winter use can take a lot out of a bike and mine tend to need a lot of work after a hard winter's use.
It was so obviously I declined lol thanks for replying :-)Whenever I see anything described as "fair condition" it's usually a euphemism for being in a pretty bad state.
