I'm actually a big sunroof fan, because sunroofs let in sunlight in the wintertime. I currently drive an '05 X5 and my favorite feature bar none is the panoramic sunroof. I love having the sunlight pour in on a sunny day in December or in the middle of the summer on the highway where I don't want the top open. I actually have considered the Mini Cooper for that very reason, but I think that I've settled on replacing the X5 with a 135i with a traditional sunroof. It certainly looks large enough to keep me happy
