Hi Ant!
I found myself a Willy1 in the end and have got my original dealer mats in there for the sake of originality. You can still just about get the original mats that would have come from the dealers back in 1993 if you pop into Renault. Theyre grey, but they obviously fit the car and blend in well with the plastics. Blue mats would be a nightmare!
My local dealer is pretty rural and they even still have a few sets of dusty old Clio 16V Phase2 wheels hanging around, so the chances are theyll have loads of other old bits that no-one buys in the sticks.
