Nasty!!!
Nearly as bad as the time i lent my sister in law my RS2000 last year when i went on honey moon!
Her 'Little Angel'

had strewn maccy d's nuggets, chips, sauces all over the car!
Not only that but i think he must have been using my cd collection as frisbies as they were thrown all over the car and all scratched!
Then to top that off she'd reversed the car into the tow ball of someone's trailer, leaving a nice tow ball shaped hole in the back bumper!
