Cosmetically looks a bit worse for wear but its nothing some time, elbow grease and a good polish wouldn't sort out! Mechanically it looks pretty good with the major service just out the way including the cambelt and stuff. Personally i would go for one with climate control instead of the standard air con but thats only my preference.
The most important bit in that advert is the fact he's committed to another car. He's just told you he's got to get rid of it and i reckon you could get it for cheaper using some tough negotiation, If i were you i'd start at £7.5k knowing he must get rid soon and try and come to a deal
Hope this helps!
