I have only damaged my rear bumper once which was around 3 weeks ago through carelessness.
I had a warped (!) rear bumper from new in the number plate area which was, after a huge argument with VW, replaced under a 'goodwill' gesture.
Unfortunately, my rear bumper issues turned into a long thread and have susequently become a topic of great hilarity but not to me.
But I won't deny any of you having fun at the expense of my rear. :smile:
