If it ain't broke, don't go broke.
Link below for folks thinking about second hand BMW...it would be good to see the actual study details.
I have to say my 03 - 530 has been worse than my 528. Depsite the 530's high ranking in consumer reports, it has had quite a few things go on it, that I would not have expected for a premium brand. Important to get that PPI for the car you are interested in and do some research on this forum to see what to look for.
