Besides being the obvious scams like transferring funds etc. If I were to buy something on CL's I would meet up and inspect the item, then what? Should I write up some kind of purchase agreement? Write a check? Cash? Check would probably be better right? I don't know about the problems that MPB's have so if you guys could give me the lowdown for the "known" problems with it, that would be helpful when I look at the item.
