Any chance the doctors receptionist might be feeling helpful with the appointments book? I guess they won't / can't give the details to you, but maybe if you kick up enough of a fuss over it being an offence, and to pass details to the police.... Granted, you've got two layers of apathy to break through plus the chance she'd just parked there to go to the cash machine, but it'd be worth it to see the look on her face when you turn up with the repair bill for her.
Had to send my first TF to the breakers after someone bent the rear quarter under cover of darkness, so I know how annoying it is
