Sorry about your car Brenbo, glad you were able to remove the damage.
The problem is not just exclusive to big 4x4's though, but I know exactly what you mean. We have an Amarok, and finding a space it can fit in is often difficult but with a bit of searching, it is possible to usually find somewhere that doesn't pose a problem for others. That said, I've had 3 lots of damage to my R sustained in car parks, all inflicted by cars, and in one case a very small fiat that bashed its door into mine as I was sitting in it! Consequently we now use the big 4x4 for supermarket duty because of this! So it's more a general couldn't-care-less attitude that seems to have pervaded some of society that leads to this situation where you take pot luck when entering any car park. And the usual precautions of finding isolated far flung spaces is no guarantee, not when a car will drive across over a 100 empty parking spaces to cosy up next to the only other car in sight, as was the case with the fiat. This coupled with the fact that parking spaces are still quite small despite the general move towards larger vehicles, which needs to be addressed by councils and providers of car parks, means public parking is Russian Roulette.
