I was wondering if when Trevor and Kenneth did the test drive if they drove with the windows down? We know there's not currently a sunroof option so driving with the windows down is a nice way for some "fresh air". My real question is, how much noise is there driving with windows down? Some cars are horrible with the "booming" sound and some cars are designed so the wind passes the window without noise. What was your first impressions driving the M3 on this topic?
