Write to Renaultsport. I'm sure they'd treat it more carefully than the Renault UK dealer network, who I must say are absolutely shite.
Having owned Toyota, BMW's and Porsche's, Renault's service, parts and customer service dept's do not cover themelves in glory whenever I have to deal with any of them. One of them didn't even now what a Clio Trophy was.......... Needless to say I didn't use their 'expertise' on my car.
