Number-Mixing Tactic

The Four-Square

One worksheet puts four moving numbers in front of you at once. Your counter-move is to split the transaction back into verifiable parts.

Track the Four Variables

The Simple Version

A four-square worksheet commonly combines vehicle price, trade-in value, cash down, and monthly payment. The format is not proof of deception, but it can make it hard to see which number changed or what the vehicle and financing cost in total.

A lower monthly payment can come from more cash down, a longer loan, a changed trade allowance, or a different amount financed. Circling the payment does not tell you which lever moved.

Start with a written, itemized out-the-door price for the vehicle and every fee or add-on. Then separate the trade and financing: evaluate the trade against outside appraisals and compare loans by APR, term, amount financed, finance charge, and total of payments.

Keep copies or photos of every worksheet you are allowed to retain. Rewrite each proposal into your own columns. If the dealer will not give you enough detail to reproduce the arithmetic, you do not have a usable offer.

Counter-move: “I am not negotiating four moving numbers. Give me the itemized out-the-door price first. We will discuss trade value and financing separately after that number is fixed.”

Immediate Action

Vehicle Price

Selling price plus each fee and add-on

Trade Value

Allowance, payoff, and resulting equity

Cash Down

Where each upfront dollar is applied

Financing

APR, term, amount financed, and total cost

One Decision at a Time

Fix the purchase price first, compare trade second, and choose financing third. Cash down is a funding choice, not a discount.

Audit the Final Contract

Match every final number to the written deal you accepted. Stop if a product, fee, rate, term, or total changed.
