Update:
I spoke to the owner of the car today. He said he filed a claim today with my insurance company and the estimate would be about $500-800.
I asked for his insurance information again but he said he does not have it since he just got a car, not even a temporary insurance card.
He said he is on a rental now.
Concern: What is he had no insurance? I don't have any uninsured motorist insurance either.
