Have you ever been in a R56 MCS at full throttle? If not, get yourself down to Stratstone Mini Dealers in Tring and ask for a go in their R56 MCS JCW stage 1 tuned demo' car. And then tell me that 193bhp in a Mini is a waste of time? Once you've got, you WILL use it, trust me.
And regards to "traffic management systems etc", there are miles of roads that you can still have heaps of fun with, especially in Bedfordshire! You just got to know where to go!
