Lesson 1. Don't take your pride and joy shopping. If you must, don't park it closest to the entrance. Higher volume traffic, including families with kids, and old people are in higher proportion. All of these groups are "Car door unfriendly".

I hope this helps you all.

ps. The parking next to a good car is a great idea, unless it's close to the entrance, A Minibus full of kids will replace the nice car before you return, and they'll dent up your car good.
