You know all the reasons to buy one - didn't regret buying mine at all - went from 12k to 110k in mine - never scrimped on servicing or tyres - Conti's wore about the same as Michelins but were typically £200 a set cheaper.
Problems with mine - new dash computer needed when it switched to metric units instead of imperial - couldn't be fixed, was repared at great cost under warranty - leak from crank
seal fixed under warranty at c. 25k - recall for new clutch master cylinder - problem with cracked inlet manifold at c.73k fixed (again at great cost) under Renault extended warranty - blown
seals at 110k - which has most definitiely not been fixed under an aftermarket warranty.
Other than that, one set of rear pads, two sets of front pads, one set of front discs. Oh, and one battery at 108k - make sure it has the right size battery fitted as GSF, Halfords etc try to tell you an 096 fits - it's not right, it's too small.
It was dealer maintained all the way bar one specialist service and an ex Renault tech who set himself up.
My only regret is not selling it sooner.....
If you're looking for a superbly maintained 2.2 diesel VS with leather 2004 on a 54 that needs a little work, buy mine......
