*UPDATE*
As of right now, we can not order any more of these....we hope this is just temporary........however we still haven't heard if BMW is going to fill the numerous orders we have open for these. We have received some, and filled all orders we could in the order they came through....but we do have a lot still waiting on the parts. We'll update again when we hear more.
No idea why these, of all things, would be blocked.
