EDIT: It's sold. Thanks!
Traded for this a while ago thinking I wanted to put it on my 318ti then decided to keep the stock wheel. Thought I'd offer it up here if anyone's interested. $50 shipped (Paypal). They seem to go for ~$150 in perfect condition.
Mine's in great shape except the little plastic tab on the back of the hub is broken, but I still have it and it's a clean break (banged it on the @$#%& doorway bringing it upstairs for pictures...) Anyway it would be pretty easy to glue back on there.
