Do Car Dealerships really pull this stuff?

The 'four square' gimmick.

At the heart of it all is the "4-square," a sheet of paper (sample above) divided into four boxes: your trade value, the purchase price, down payment, and monthly payment. This is supposed to help you and the dealership come to an agreement, but as you'll see, it's really more akin to three-card monte dealer's deck of cards. Many, but not all, dealerships use this tool.

So, at this point, we'll assume that you've gotten everything square and you're ready to close the deal. Sometimes, if the manager feels especially nasty (or has gone a few rounds with you via the worksheet), they'll come out of the tower and say "Folks, I'm (Douchey McDouchebag), the sales manager here. Congratulations! You've just bought a car! We were able to get the payments to $310 - I know you wanted $300, but that was the best we could do. That's close enough, right?" They'll nod their head (another psychological trick to get you to agree), and almost every time the person says "Yea, that's fine!" The problem is, they didn't realize that a $10 payment bump over a 5-year loan nets an extra $1k in profit for the dealership. It's called "the $10 (or $15, or $20) close", and I only saw it fail when a person was really, really exasperated with us. The deal ends, and you wake up in a year realizing that, somehow, you're $6,000 upside down on your car, while the dealership is laughing all the way to the bank.
