Magnus is right - it's a fine line. The SoCal and NorCal dudes both seem like genuine enthusiasts of automobiles, and entrepreneurial. And no harm is being done. And who knows, maybe one of the crowd will see the light and realize that M3s just really aren't that capable when it comes to going fast (as me how I know!) and get a real car.
Nothing personal, but I tend to ignore them. The last thing in the world I want to do is go driving on the public way w/ a bunch of people (younger males it seems) who I don't know. Partly because it might be dangerous, but mostly because it would be boring.
