The most important lesson to learn from this is that you probably seem like a real sucker. You need to work on your image so people don't even bother trying to scam you. You're from the Midwest originally, right? The slick BMW salesman probably made a bet with one of his work buddies that he could get you to cut him a check for $1500 by bringing up some notion of "moral responsibility". He's freerolling here. Probably something like 30% of Midwesterners, Southerners, or people from other rural areas would actually give this guy the money. He makes a two minute phone call, and gets ~$500 in +ev. You need to adjust your image so that it's not even worth for him to waste his two minutes making that phone call.
