It's far from unknown for the clutch/DMF to fail on these - as I'm sure you're already well aware. At over 100k it should be already sorted - if it was going to be an early failure, it would have failed by now, it'll be just down to wear and tear now. Give the clutch a bit of a strain by accelerating fairly strongly from about 1600rpm to 2600rpm in 5th or 6th gear and keep one eye on the rev counter - any surging from that may indicate the clutch auto adjuster...... hasn't or that the clutch may be in need of further attention ! Any bad rattles at tickover may indicate the DMF has seen better days.
Check the drivers seat is comfy - it may seem a strange thing to say, but in rare cases the foam base can start to disintegrate and you end up with an uncomfy seat which on long drives isn't pleasant. If it's got Sat Nav - check it works and locks on to satellites - the antenna can fail (probably water ingress), a cheap fix is a 20 Euro antenna from ebay fitted to the inside of the windscreen. Similarly, the outside temperature gauge can give dodgy readings - replacement is relatively straight forward. Check for bangs/clonks from the front end when going over bumps - anti roll bar links wear out easily but are not too difficult to replace - same with the rears.
I'm sure drivers of the 160BHP variants will chip in with what to look for on that model revision
