If you like the stick on stripes and can live with no trim in the back and want to use it for an occassional track day then yes, and it will hold its value better than a standard model too.
But of you want to start adding extras it doesnt already have, like auto climate, sat nav, heated screen etc, dont think it has these as standard? then to cost will go up considerably.
Might be better off with the standard JCW
in that case as its 5 grand cheaper or there abouts?
