You can get it fixed.
You dealer should be able to refer you to a place that fixes them.That should be much cheaper than buying a new one.
Otherwise the dealer of course can get you a new one, the wheels are rare+new enough, that your ebay/junkyard options are limited.
I recommend going with a repair.I once had a BBS wheel that was beaten up years ago and it got sent to a plcae in Chicago for $140 and came back as new.
