Up for sale is the front license plate mount (black by default), this is for North American plates, and is for preface lift (2003-2005) models.
Its brand new, still in the BMW plastic wrap with parts sticker still on the wrap.
I ordered it before I took delivery of the car, but the used dealership I bought my car from had one installed for me, and this new one just came in the mail.
$25 USD + shipping.
Note: It doesnt have the 4 screws, but the 4 screws are literally less then $0.50 each.
