What is the M Sports package II on an Xi?

So I have been searching for an answer to this but I can't seem to find one. My car is a 2004 330 Xi with M badges all over the interior. I did a vin check and it says I have the M Sports package II. But what is that other than all the stuff labeled "M"? I believe that there is no sports suspension for the Xi's. So is it more than just interior detailing?



Thanks,

James
