Take the purple truck to work with door edge protectors on it. "Accidently" fling the door open into her car. Remove door edge protectors.
Revenge is best served cold.
The last person that rested their door on my truck lost a mirror. One woman actually had the audacity to say "your truck is so scratched up I didn't think you'd notice". I said, "It doesn't matter whether I notice or not, it's not the right thing to do. Especially when a person backs their butt into the door proceeding to dent the box of my truck like you just did." She proceeded to tell me that old vehicles like mine shouldn't even be on the road anymore. I pretended to drive away as she went into the store. I parked, walked back, and left her passenger mirror dangling by the wires.
