The BS definitely has to be seen in the flesh, has a lot of 'presence'. I would personally spec it with the carbon fiber package over that silly rear wing, but other bits you get as part of the Track Pack are pretty cool. I am def a BMW guy, but in this case of asked to chose, I'll check the AMG BS box.
