Most obvious MoCo external antenna mounting spot would be on top of the RECESSED leather dash, with a "XM recessed mounting rectangle - adapter kit $49.85" -2 x 2 inch piece of steel black powder coated with 4 holes drilled into it to make it impossible for non CVO owners to use a CVO leather dash and vice versa. The MoCo would care if enough folks stopped buying their bikes and their weird-assed accessories that are highly individualized for each bike.
Agreed on the BMWs of it was just about handling, speed, and power. The Beemer guys around here dress like they are on an Alpine riding exhibition and quite a few are too cool to wave. Or maybe they are adding the extra latte by hand switch to their caramel latte machiatta espresso about to be dispensed fresh ground & brewed from their BMW on handlebar espresso machine? 
On a birghter note, am considering blasting the stereo until the speakers blow out so I can upgrade quicker and not feel as bad about apending $$$$. 
Make no mistake about it, I truly love my bike, and hope it will be with me for many years, as I have no intention of owning anything else in the next 5-7 years. But with some of the problems you guys with the 110's have been dealt because of the MOCO either not sufficiently testing, or doing so and knowing full well that the problems are there and just letting the consumer deal with it after the fact, I would have lost my chit in a couple of cases. I'm not talking about just a leaky gasket, but after two or three times with it, it would not be a pretty picture, just for the principle of the thing.

I have thus far been fortunate, or been able to fix the small things myself, mostly because I enjoy the tinkering.
I know exactly what you mean about the Beemer people (generalizing here)....they wear funny clothes.

Most of 'em around here will still wave though. They probably think we're even weirder, with our devotion to not only the bikes, but the clothing as well...."The Look". And devotion to, by any sane measurement, a vastly inferior product technologically and mechanically. But they don't unerstand...
Just put "Whipping Post" (the Filmore East version) in the CD player and crank her up with full bass and treble...or just the entire FE CD....that should do the trick. I'm still waiting on those Bose helmet headsets...
