I don't afford a Porsche. But if I could afford to buy one, I would still not buy it unless I could afford to park it anywhere. That is, there is a difference between affording to just buy a Porsche (perhaps as a status symbol), and affording to buy a Porsche and use it without care. I don't think that it takes a lunatic to park his DB9 on the street, just someone who bought the car just because he likes it and can do it. The feeling I get is that you are implying that a Porsche is a status symbol, whereas the owner thinks it's just his car, and does not care what any of "us proles" think.
