My 'champaigne' (silver / bronze) Outback picked up a few bush speed stripes over new year, but they aren't really noticeable until washed. I'm hoping they will buff out. They would certainly be more noticeable if the car was a dark colour.
To put it in perspective however, even if you try and keep the car pristine and were never to go off road, some fcuknuckle in a car park will ding you with their door.
poop happens, so better that it be as a result of you having fun!
Incidentally, just another reason why I wouldn't buy a new car - let the other bloke take the hit on depreciation!
