Your situation reminds me of all the times my past cars and present rogue have been hit in a parking lot. So I feel your pain.
I remember when I went to my Nissan Maxima and found it vandalized. The sunroof was broken into and my window was pushed open from a closed position not to mention all the dents some a**hole did while trying to break-in. My stupid self had to park next to this truck that had a trailer attached. I'm not saying they did it, but maybe they were jealous who the heck knows. I was so upset.
Anyways, here are some tips. These are not mine but most people know. I never really knew parking next to expensive cars worked since I just thought rich people dont care or its just an expensive car banging into your parked door. But I guess it makes sense since they don't want to mess their door. I guess thats me too.
Also keep a digital camera in the car, so if somebody parks next to you car and dings it, you can take a picture of the vehicles, paint transfer, and license plate so you can report them to your insurance. Also good for real time accidents.

Car door ding prevention is all about finding the right parking spot. While I follow my parking rules instinctively, I have racked my brains and put my rules on paper. My rationale is that this could benefit some people, and prevent car door dings.
1) Always park away from other cars when possible. A short walk to the mall or store will do you good.
2) Try to park in the end cap parking spots. End cap parking spots are usually wider and you can park closer to one side. When parking in an end cap spot you only need to worry about one side of the vehicle.
3) avoid parking next to large cars (i.e. Buick lesabre circa 1970’s –1990) because they take up more space and have big heavy doors. Avoid parking next to old and neglected cars that look like rust buckets. Avoid parking next to minivans with a bumper sticker that says “soccer mom”. the driver of these vehicles classes, do not care about their vehicle’s appearance. More likely than not they will plant a few car door dings on your delicate car door paint and never look back.
4) If possible park next to small cars (i.e. Honda or Toyota) or expensive cars (i.e. BMW or Mercedes).
5) Use car door protection whenever you park.
While there is no guaranteed full proof way to prevent car door dings and dents, a little common sense and caution will keep your car door ding free and looking great.

1. Never park downhill on a sloped parking lot.
2. Never park next to a shopping cart return.
3. Always park in the right-most parking spot. As close to the curb as possible, or ever better when there is no curb.
4. If the parking spot is too narrow to accomodate a full-door swing in #3, find another parking spot further away.
