Here is an example...When I was selling my 540 I was giving a test drive....We passed a sterling M and I immediately did a FAST uturn to hunt him down....I had not seen a sterling M5 in person.....after about 2 miles I found him in a local mall parking lot and he was happy to talk about his car, why it was so dirty, why he had it debadged, etc. Some can be jerks. they are all over but generally I think M5ers are an ok lot, save the obvious few.
