In my case it wasn't that: The dealer straight up imagined a sale they wanted to have, and were quite rude to me.
Me: "I want to buy one of the cars you advertised in the newspaper." (It was 2003)
Them: "We don't have those cars."
Me: "But you're advertising this sale."
Them: Poker face.
It wasn't like they said, "Oh, yeah, that was a popular sale and they sold out." It was very clear they advertised cars they didn't have so they could divert me to a more expensive model, and it wasn't like they offered to call another dealer to ask if they still had inventory.
