It's an interesting discussion. To play devil's advocate (and nothing else), one could argue that forum members take better care of their cars because they are better informed about their maintenance, etc.
As proof of that, one local dealer in my area had three blown M3's in the shop at the same time three weeks ago. Very likely if these had been forum members, you would have heard about all of them. So did they all abuse their cars because they are less informed, or is there really a problem that is only now beginning to be discussed?
Again, devil's advocate...and nothing more.
