Seem very hard to find second hand! If I can sell my 182 wheels for £260 that's not so bad...
£580 - £260 = £320 for a new set of turinis. Sorry but I don't know what PCD fitments are.
They will need to have the correct ET and PCD for the Clio I would imagine. Not all wheels are standard fitment, they will need to be made to fit the Clio basically. Not sure if all Turnis are in the same fitment or not. Plus KTEC site is cheaper is it not?
£260 with or without tyres?
