That would be a tough proposition for simply becasue I really don't know anyone other myself, my wife, my sister in law, and one of my friends who has a BMW. 3 of us have 5 series. I have 540, sister in law has 530, and my firend has a 540. All of the 5's are the E39 model (1997-2003). 1998 540, 2002 540 and 2001 530. None of us have had any issues. Wife has 2004 330 that is only a few months old so we haven't had anything wrong with that. Other than that I don't know anyone with a BMW. I did have a buddy with a 1993 or so 318, and I think he rebuilt damn near that enitre car over his ownership of it, but that was about a 8-10 year period. I know only one person with an Acura TL. He hasn't had any problems, but his car is fairly new and he leases all his cars. His is not the current model, but the model prior. Very nice ride - smooth and quiet.
