About 6 years ago, Lan's car was due for replacement. It was almost 20 years old and parts were starting to become hard to find. One afternoon when we were coming back from the market in Sunnyvale, we decided to stop at the Ford dealer.
They were having a sale on the Ford Focus, Lan likes small cars, so we thought we'd check one out. We talked with a salesman who took us for a test drive. We didn't like the Focus at all, but decided to have some fun.
We went into the salesman's cubicle where he started the car salesman's pitch. He told us we could buy the car for only $19,800. We countered with an offer of $18,900. He went back to the salesman's secret room to, "Check with his manager."
When he came back, he said we could have the car for only $19,500. We countered with an offer of $18,200. Every time he came back with a new offer, our offer went down another $500 or $600. After a few iterations of this, he said in frustration, "You can't bargain that way!"
We said, "You bargain your way and we'll bargain our way."
When we got back to our car, we both burst out laughing. We didn't buy a car, but we had a lot of fun bargaining.
