I know how you feel. With just my current Golf I've had:
1) Some old duffer with windows so steamed I couldn't see his face drove into the side of my car while I was stationary in traffic - wing *smash* (does he brake, no..) drivers door *screaming and scraping of metal* (still no sign of stopping, surely man, notice the resistance for pity's sake, not another panel) *crunch of rear door and scuff across bumper* and away he potters and stops 10 metres on. A good lesson in self control against my instincts which were screaming "grab that scrawny chicken neck and shake some sense into him".
2) The REGULAR shopping experience of car spaces being inadequate for large vehicles; so when you return to your car which was formerly strategically parked between 2 tiny nissan micras you discover a large SUV or 4x4 next to your car with an even larger 4x4 butt poking out and rubbing their door against your paintwork whilst they examine every item of their shopping. Rage!

And don't get me started on keying cars. I would dearly like to locate the little vandals that do this - some glue sniffing little idiots did this to my partners' car. I would dearly like to locate the little stains of humanity and grind excrement into their precious ipod speakers, "just for a laff, like".
