Recently I was involved in a minor collision in a college parking lot. I scratched the car in front of me and I admit I am totally at fault. I spoke with him after the incident and he claimed that his car was just painted in a stock-black color. However, upon speaking with him again two-weeks later he claims that his car has a metal-flake paint that he did not know about. I think I am being scammed and that he wants me to pay him cash. Also I have heard that minor accidents on private property are 50/50 liability, in that we each pay for our own damage or something. Does the fact that he verbally said he had a stock color mean I only have to pay for that, and does this 50/50 thing mean anything?
