i think comparing a 1.2 clio or 1.4 clio to a 182 or 172 isnt fair.
you just compare that clio above to a current, 4x4 ride height, grey plastic bumpers, 15" poop wheels and knowone can say that the current shape is worse it looks about three times as expensive,bigger and classier.
As how the current RS will look compared with the old RS i cant say anything apart from it will be exactly the same speed due to weight and if BHP pertonne is anything to go by (usually is) then it will be about 1/2% slower at 197hp with 150kg`s heavier than a Cup if not 180-200 with fluids and extras fitted.
id still get one after the cup as you can only live in the past for so long i.e williams and valvers are getting seriously long in the tooth and 172MKI`s are heading that way at nearly 6yrs old once you pass the 10yr barrier you best getting a new motor as airbags need redoing and things start to fall off etc..
