Yeah, I think that's about it.
The Chilli pack wasn't available in Australia until the MY05 model change. My pre-chilli model (April 04 build) almost has the same options, save the wheels (I had aftermarket wheels waiting before my car arrived) and I have
DSC instead of HK.
To the OP, also keep in mind, that all Australian spec Cooper Ss from January 05 build onwards have a limited slip diff.
