? For those who have recently bought or sold a vehicle

Anyone who tries to rob me will be leaving with more holes they came with. Free of charge, of course. And what are the chances you are going to lose your cash or have it burn up in a fire before you deposit it in the bank??

Regarding counterfeit cash, that's a legitimate concern, but all you have to do is take your time when you're counting the money. It's really that simple.
