I think he deserves 4 grans, that son of a bitch is totally responsible to pay whatever costs u had. I had same problem a long time ago. This some Nepali son of bitch drove my car n hit 2 cars at the parking lot. We fled but after a week we got caught. Since it's been just first semester in USA for this Nepali guy,I told the insurance that I was driving. I had liability only so my insurance fixed others car like almost 10 grans n my insurance went up from 40 to 90. That Nepali son of a bitch just gave me 500 when it costs me 1200 to fix n i really didn't  fix all stuff otherwise it would have costs me 2 grans. 
      So dude ya take him to the court. I regret taking responsibilty n paying too much on insurance. That cheap son of bitch told md he will pay me all when he gets a job but he hasn't yet. Seeing your posts I remember my incident n my anger towards that cheap mothertruker is so high rt now. Had it been Nepal I would have caught his tongue coz a man who can't keep a word don't need no tongue.
