I've got a similar bump on my rear M5 bumper...

I went to watch a movie and parked on the street. I left a ton of open space for the guy in front and behind me. I come back and see white scuff marks just like this.. I mean seriously, How the F do you hit someone with that much space in front of you!! Needless to say I still have yet to get any closure on that situation.

Lesson learned, Dont park it on the street!


And to think, they have flying cars now... I wonder how many people will die from that!

 

Why do I get the feeling that some the people who said get "hope you get the guy" probably would not have left a note also as i think leaving a note is the exception not the rule.
