Almost a month ago, some drunk kid swiped the side of my car. It wasn't gigantic, so i just exchanged numbers. I asked for his registration and insurance info and stuff, but he said he didn't have it cuz it was his girlfriend's car. So I just grabbed the plate number and told him I'd call him back with an estimate. I've tried to get in touch with him for the past 2 days and I guess he's avoiding my calls. Is there any way I can find the owner's info using the plates, without having to pay some fee or getting the police involved?
