Its a personal choice, for me I couldnt justify the cost plus the money I would lose on my 182. You also have to remember that you lose a fair bit of kit as well, leather in front and back (although you get the lovely recaros), cc and xenons.
However if you like the colour/looks and want the best handling clio ever made then go for it
I guess it depends on what you really want, do you want something more rawer than what you already have? if so get the trophy
