A friend in my local BMW CCA Chapter recently bought a cream puff 2000 Z3. It has the Harmon Kardon stereo system installed. Between the seats it appears that there is a removeable top/lid type thing. The owner hasn't removed it fearing that it really doesn't come off and in an effort to do so may damage it. Will anyone that knows for sure tell me if this top/lid is one that can be removed etc? Thanks.
