Came back to my M3 this afternoon in the supermarket car park to find a shopping trolley parked into the passenger side rear qtr. done on purpose, too, as they had managed to ding the metal, and these are not soft like a Subaru (ask me how I know...). It wasn't parked badly, but was in an electric car charging space, just like four other cars. We'll it does have a battery... I can only hope it was some green soft arse that needed a charge for his stupid battery powered joke, and subsequently didn't make it all the way home. Grrr.
