Well, as much as you're going to possible get a better spec (as you would for the top model), has no one considered insurance group and costs involved? For most people that don't have 5 full years no claims and arent over 25, are going to get a hefty insurance quote. I can only guess the JCW will be a group 19 or 20 car considering it's power.
Anyway, I may consider a JCW in 2/3 years time
. The original R56 S is enough for me
