No more cash $$$ at car dealers

I'm not quite sure how the conversation started, but it somehow ended up on asian gangs in So Cal. Then one of my buddies had mentioned he asked one of the car dealers down in the OC/Little Saigon area if people bought cars with cash. The dealer said they use to until around four years ago or so. Apparently, at that point, anytime a person bought a car in cash (the cold hard kind, not a check), it immediately alerted the IRS. Drug dealers don't really like having the IRS tracking them apparently.
