Thanks for the replies.
True, the question was vague.
Been driving BMW (e83) for the last 7 years and very happy. Only complaint is city driving mileage, but apart from that see no reason to switch.
I have a friend who swears by Mercedes, so was just looking for info/anecdotes to counter his claims, thx.
