Yeah the bitch obviously doesn't seem to care about the body of her car (or her body), so I'll have to do something that she will care about. I'm thinking a tire, a windshield, head/tail lights, and possibly stealing both her license plates. All in all, that'll leave her generally fucked, without literally trying to kill her. The target is the car, not the bitch. ...As much as I'd like to indulge a little.
Now, I understand where you come from man. I fully believe no one loves their car more than I do, and I would be exactly as pissed as you but..
Personally, what I would do, find the car, smash a tail light and walk. An eye for an eye. If she happens to "That must have been the guy I hit!"
It would go something like this.
Woman> "You smashed my tail light!"
You> "I did? how do you know it was me"
Women> "You did it out of revenge cuz I hit you"
You> "You just admitted you hit and ran, commited a felony against my property, I suggest you take your tail light and leave before I consider talking to the authorities"
Women> "..."
Now, if you dont take my advice and run with what you got planned, thats all good, just dont be stupid about it.
It's all good to think about what you could do, but yeah, last thing I would want to see is a goodbye post cuz your gettin locked up / fined out ass.
Edit: Could always do what my dad did to a coworker on his birthday. Take some chocolate cake and smear it on the wipers, and put an assload of confetti in the Outside to Inside Vents just above the hood. Turn on the AC and HOLY SHIT ITS A PARTY WEEEEEEEEEEE!
