whatever you do, dont accept the cash, go through the insurance, once he finds out how much it will cost in cash, he will deny ever doing it, get your camera, take fotos of your car, and his car ASAP, before he wipes off your paint from his car..... Hes tried deniying it once he will do it again, thats whats happened to me... get the police out, because he could be pissed, on drugs etc.... and make sure you get the witneses to confess to the police everything they saw, make sure the guy knows you have witnesses ok. Speak to him tommorow and get his insurance details, if he refuses, fone the
