These are quirky (distinctive?), but very well-designed comfortable & spacious family transport. Whilst mine was running well - I loved it.
However, there are a few clouds on the horizon worth bearing in mind;
does the cambelt need changing - quite expensive
2.2 can have
check & double check the operation of all electrics, and ensure that all the warning lights illuminate on start-up, then go out as they should
Tyres can be costly for 'branded' versions
Body-wise, they age very well, with any corrosion really showing a neglectful owner or a botched repair
worth a punt for the 'right' money, but be prepared for some big bills and plenty of "a what?" when you book it in for repairs/buy parts...(even from Renault).
These cars aren't loved by the trade, so depreciation will be severe - which is less of a problem if you plan on hanging onto it.
