Is £500 for 2011 Spesh Allez Elite a decent price?

Looking around for road bikes (it'll be my first - have a Sirrus at present) and was quite tempted by the Triban 5 from Decathlon (or possibly 7 if I feel flush!), but a guy at work is selling an Allez Elite 2011 model. He wants £500 - is this reasonable? Anything I should look out for?
Seems quite a lot of bike in comparison (full Tiagra) - although that said the Triban 7 is also full Tiagra and only £99 more brand new....
Have I just answered my own question?!!

Only info I have on condition before contacting the seller is:
"It has had two new inner tubes recently, I have also had the gears indexed and the rear bearings and races replaced, and brakes adjusted."
Assuming there's a typo or something in there - 'races replaced'?? Also not sure what the rear bearings refer to (I'm a complete novice to home-servicing!).
Only worry is that this may indicate quite a lot of use.

Good frame for the money though, as long as it fits you!
