Well, at last, I have taken delivery of my new 2015 Z4 35i. Love it. In the trunk were the floor mats, the cover for the pass through hole between the trunk and the cockpit as well as the through loading bag (I guess primarily for skis), the rack for the skis, the front license plate bracket, and the bag of screws and washers to mount the license plates. There was something else in the trunk and for the life of me I can't figure it out. Attached are two pictures of this mystery part. Can anyone identify what is this part? I am also attaching a picture of the car on the day it was delivered (yes, I had them leave some of the protective tape for me to remove later).
