I saw a really nice flame red 172 in a shopping centre car park once, it looked realy nice, but something just wasn't right with it.
My mum (who came shopping with me) looked at it & announced 'its got a sunroof, that's not right is it as you dads doesn't have one' When I looked at it a bit closer (apart from the sun roof lol) There were a few other bits not right. The car did have a full 172 interior in it too.
Personally, I think that an all out replica is a waste of time & money (unless you actually put the 2.0 engine in it too) Much better off doing other subtle things to the car instead as some non renault sport clios on here look fab.
