My car has a bunch of them NOW! People need to pay more attention to that stuff. I hate it when they just swing their door open. I try to stay away from cars with long doors - the old school cadillac's.
We have a bunch of dings on our car too. I try to be extra careful when opening the door near other cars because I know how bad it feels to see new dings on your door.
I've seen a car pull into a parking spot, and park over the line so as to take up two spots - and it was totally unnecessary (I think he just didn't want anyone to park next to him, so he selfishly takes two spots). So I park right next to him and blast my door open to scratch up his car. I don't mean to judge him, but he was a selfish bastard that deserved it.
i have a couple dings and that's the cost of parking in public and daily wear and tear of a car. i have no problem with a dent or a ding. i can't stand people that treat cars like babies.
Being that I live in San Francisco, I can't believe that people don't expect their car to get dinged. Yes, I know it's a shame, and you're not looking to get dinged - but come on, a car has a function, and it's not just for looking at.
Morale of the story: Don't park next to shitty beat-up looking cars.
