Unwritten rule to selling a 4 door

Back in the day before digital cameras and the internet you had to look in the paper for cars. Inevitably you'd find the car you wanted with a good description at a reasonable price. When you called the first question asked was is it a two door? After being assured it was, you drove to look at only to find a four door sitting in the driveway.

Of course we'd ask, "You said it was a two door on the phone?"

They typical response was, "Well yeah, two doors on each side."
