Remove them and be done with it. I did and I am having little covers built for the bare rolls bars in the same color and the interior. I could not stand the loss of vis and did this a couple weeks after getting my car but am just getting around to this now. The plastic covers that house the roll bars don't look all that bad.
To remove them just pull up. I mean pull up hard because it take considerable force to get them out. Seems like all my BMW convertibles needed lots of force to do this.
The covers don't block any vis now and once I get the plastic covers off and put the roll bar covers on it will look pretty good...
