balloons on used cars?

Why on earth do used car dealerships tie balloons on the antenna’s of their cars? Yes, it draws attention to the car, it says…“look at me, I’m such a piece of shit, I have to try to divert your attention away from that oil leak with this 8 cent balloon”. Those places are traditionally trashy places of business, why add to it?

Movement attracts the eye, and it’s cheaper than a flashing light/spokesmodel.
