For a 10 year old car that is fairly low! - Average of 10k miles a year would put it 100k average for year!!
If you are after a brand new Williams then thats obviously the wrong site for you as there will ever only be one Clio Williams. If there was one with near zero miles I doubt you would ever be able to afford it
Renault got it right, the Williams was always described as "superb handling" "pocket rocket" etc. - They would have to come up with something special to carry on the Williams Clio - It was a venture for the sole reason that they could compete in the French rally (and others I think!).
The 182, 172 etc. is what Renault have learned from cars like the Williams and are all described pretty much the same as the Williams - but they have no reason to make a special edition - The Williams is a piece of history - A new day Williams would be a badged up 182/172 which as it stands is already a superb car!! - Then theres the V6 which covers that area for people that want a clio gone mad and totally different - Why would you want a new style Williams with that sort of choice??
So I tottally disagree with your idea - Some people
By all means stick some gold alloys on a blue 182 and stick on some Williams stickers - but whats the point? - It will always be 182 - The Williams was different and can never be recreated.
