My end result from Renault... Nil!!!
From a mechanic's point-of-view, Renault U.K are pretty bad with parts identification and prices, just ask any mechanic you know who has dealt with them.
Their cars are pretty cheap to buy but they get you in the parts department.
My uncle was a parts manager at a main Renault dealer; he said Renault parts are a nightmare - they use whatever they have at hand, so two identical looking Renaults from the same year can have completely different makes of components. That was a few years ago, but I doubt much has changed.
