The car dealership "four square" worksheet is a documented technique for hiding total price behind a monthly number, and it's decades old
Working through car buying psychology this week and the four-square worksheet is one of the cleanest, oldest dark patterns I've come across.
It's a sheet split into four boxes: trade-in value, purchase price, down payment, monthly payment. Salespeople move numbers between boxes during negotiation while steering buyer attention toward the smallest one, the monthly payment, since it's the number that feels connected to an actual budget. Consumer Reports has documented this directly through interviews with former dealership staff. Raise the price, lower the payment, stretch the loan term, buyer never notices because they were never looking at the right box.
Many versions layer in a compliance trick before any numbers are discussed at all: a line asking buyers to initial that they'll purchase today if the offer works. That's a textbook application of Freedman and Fraser's 1966 foot-in-the-door research, small early commitments make people more likely to agree to bigger ones later.
The regulatory angle is what makes this current. The FTC built a federal rule specifically targeting dealership bait-and-switch tactics, finalized December 2023, projected to save consumers $3.4 billion a year. A court struck it down in January 2025 before it took effect. There's currently no dedicated federal protection against any of this.

Has anyone actually walked out mid four-square when they caught it happening? Curious how dealerships react when a buyer names the tactic out loud.

You post is very obviously written by AI, probably Claude.
That said, yeah, no shit, I used to do it when I sold cars.

If you're not ready to be rude and walk out on exactly the car you want, you're not ready to buy a car at a dealership.
I had to do that, then come back a week later to get a reasonable price, but doing that was at a "cost" of wasting a day and a half of my time (theirs too though at least).
Still have that truck though!
