This is why you pay ridiculous amounts of car insurance.
In the meantime I'd track the ****er down...look at the level the car hit you, the shade of the blue, any regular employees there, people parking away from you, blah blah blah blah...
He/she is not going to fix their car with insurance money, so check that out...if their paint ain't perfect and their car is blue...keep tabs...they'll never park next to you again.
