You've negotiated the price of the car, and you think the battle is over. Wrong. The real battle begins when you step into the "F&I" (Finance and Insurance) office. This is where dealerships make a significant portion of their profit, often by marking up the interest rate on your loan.

The Hidden Game: "Buy Rate" vs. "Contract Rate"

Comparing car loan rates

Most car buyers don't know that dealers act as middlemen for banks. When they run your credit, a bank might offer them a loan at 6% APR (this is the "Buy Rate"). However, the dealer might present you with a contract at 8% APR (the "Contract Rate").

That 2% difference goes into the dealer's pocket as profit. This practice is legal, but you don't have to accept it.

The Power of Pre-Approval

The single best way to avoid a markup is to walk into the dealership with a check in your hand. Before you even test drive:

  • Apply for an auto loan at your local credit union or online bank.
  • Get a "Pre-Approval Letter" stating your maximum amount and interest rate.

Strategy: Walk in and say: "I have 6.5% from my bank. Can you beat it?" This forces the dealer to compete.

0% APR Incentives: Are They Worth It?

Manufacturers may offer "0% APR for 60 months" to move inventory, but you may have to forfeit a cash rebate.

Always calculate total cost. Sometimes the rebate + bank loan is cheaper than 0% financing.

Regulatory Protection

Under TILA, the dealer must disclose:

  • The APR
  • Total finance charges
  • Total sales price

Review these numbers carefully before signing anything.
