First off,
Parkers guide says they are asking too much (others may suggest Glass's guide for when dealing with dealers but I personally just refer against Parkers & they aren't that far apart) [£15340],
Don't get caught up in all the wording on the ad as everything they have listed there is standard for that model straight out of the factory I can't see a single option listed on the front page so think about if there are any options you would specifically want (ie cruise control: dealers won't retrofit to that age of car you would need to source an independent like hazy days or similar) (I am intrigued by the apparent centre rear seat belt mentioned in the overview though seeing as its a 2+2 format car lol)
digging further in they say it has phone prep although also with a big disclaimer that is current car spec not what they are selling

, have a look to see if it has the box under the passenger seat but note: the rsap bluetooth was superseded by proper bluetooth in week 45 of that year so this car may have missed out on that depending on its build date if it was fitted (if its got the box, see if you can get the dealer to try connecting an iphone/htc to it to confirm its not rsap)
the main thing is check round that its not scratched/scraped/dinted, no funny noises when running, I can't think of anything in particular you should be looking for
good luck
