I looked at one yesterday and it was amazing looking and driving for the most part. A real "cream puff" But what should I look for on most mid to higher mileage M3's. Is there a potential timing chain problem on these cars? The dealer tells me that there isn't, but I'm sure I've read soemthing about it before. I need to know as much informatio as possible so I can make a good deal with this guy. Thanks for the help and the input.
