is planning on stealing the evidence.. your Z. However if the car wasn't a rental and the owner didn't have insurance you are stuck settling it out of court, or small claims court after his hit and run. Id come up with a dollar amount and settle it out of court. call him and say its 1000$ in damages and meet me with cash or ill have the cops called. But the right thing to do is call the cops and file a report. However i was just involved in an accident where the other driver (while at fault) did not have insurance and we were stuck with the wrecked vehicle and settled out of court. Its your call.. either way good luck.
