I paid £17 for a pair from Renault when I had my R26. They come in plain black plastic. Speak to Ads on here.
Serious ? That's ridiculous. They don't even come painted. The guy at the parts department must have made a f*ck up when I bought mine then. No wonder they are no longer there. I still have my original ones I replaced on my R26 but at that price I think I'll keep them as spares.
