The 987 door edge is very easy to be scratched accidentally. For that kind of shape, no matter what did you hit, the paint will be gone. Anyone do anything about it?
You can have 3M installed on the door edge. It doesn't look great there but if it's something you're really concerned about it can be done. Of course there's also the black plastic approach but I think that looks worse.
Always be chivalrous - open the door for your girlie. She'll think you're being gentlemanly, but really you're stopping her whacking the door on the car next to you. They are particularly vulnerable when she is drunk.
