My '04
MCS was ordered without the "sport package" and therefore I got the much better riding/handling 16" runflats with the factory V-spoke wheels. The 17" an absolute waste of time and money, not to mention they are heavier and affect handling/acceleration... They are purely for looks.
I also own a 2002 Cooper CVT, so if you want opinions from someone that owns both models, feel free to drop me a private message.
