Indeed, although I've never driven a car with them. Over here in the UK we still tend to STILL call them "wing mirrors" as the fenders are called wings here (I've no idea why though!!).....despite them now being mounted on the doors.
My personal thought is that the 8 series looks both better and more aggressive than the S550. I think BMW made the M8 what the S550 wanted to be...The BMW 8-series is a great looking car, but not as aggressive as S550.....and, hopefully, S650!
