Hunting for a new car is stressful enough, but the real anxiety strikes when you sit down to sign the paperwork. For many buyers, the negotiation phase feels like a win—until a mountain of unexpected charges appears in the finance office. Consumer reporter Sashem Brey, host of Watching Your Wallet, warns that what you don’t know about the paperwork can tank your budget before you ever talk price. Here’s how to protect yourself.
Most car shoppers focus on the sticker price and monthly payment, but the dealership’s finance and insurance (F&I) department is where profits are made. “That’s where the hidden fees, unnecessary add-ons, and inflated interest rates live,” says Brey. A 2024 study by the Consumer Financial Protection Bureau (CFPB) found that nearly one in four car buyers paid for at least one product they didn’t fully understand. Common examples include extended warranties, paint protection, and VIN etching—services that often cost a fraction of what dealers charge.
The auto market has shifted. As of early 2025, average new car prices hover around $48,000, according to Kelley Blue Book, while used car values remain elevated due to lingering supply chain effects. With interest rates from the Federal Reserve still at 4.5%–5%, auto loan rates have climbed to an average of 7.2% for new cars and 11.5% for used cars. Every dollar added to the sale price—or every unnecessary fee—costs you hundreds more in interest over the life of the loan. “The paperwork is where dealers recoup the discounts they gave you on the car,” Brey explains. “You need to go in knowing exactly what to say no to.”
In a recent episode of Watching Your Wallet, Brey laid out a step-by-step checklist for the finance office. Here are the key takeaways:
1. Get Pre-Approved Before You Shop.
Don’t let the dealer run your credit without having a pre-approval from a bank or credit union. This gives you a baseline interest rate and prevents the dealer from marking up the rate for profit. According to the National Automobile Dealers Association, dealer-rate markups can add up to 2 percentage points.
2. Demand a Complete Itemized List of Fees.
Before signing anything, ask for a “Total Cost of Ownership” breakdown. Look for charges like “documentation fee,” “dealer prep fee,” or “advertising fee.” Many of these are negotiable—or even illegal in some states. For example, California limits doc fees to $85, while some dealers in other states charge $800 or more.
3. Say No to Most Add-Ons.
Dealers love to pitch extras like fabric protection, GPS tracking, and gap insurance. In many cases, you can buy gap insurance through your auto insurer for a fraction of the cost. The Federal Trade Commission (FTC) recently updated its guidelines to require dealers to disclose whether add-ons are optional. If a salesperson says “this package is required,” walk away.
4. Read the Fine Print on Interest Rates.
Some dealers offer “low” monthly payments by stretching the loan term to 72 or 84 months. That means more interest paid over time. Run the numbers: a $40,000 loan at 7% for 72 months costs $5,600 in interest; for 84 months, it’s $6,600. Use a loan calculator before signing.
5. Never Sign a Blank Document.
It sounds like a no-brainer, but Brey reports that “spot delivery” scams are on the rise. Dealers let you drive the car home before financing is finalized, then call you back to say the loan fell through and you need to sign new terms—often at a higher rate. The CFPB issued a consumer alert in March 2025 warning about this practice.
In her investigation, Brey followed a buyer named Rachel from Houston. Rachel negotiated a $35,000 SUV down to $32,500. But in the finance office, the dealer tried to add $1,500 for a “protection package” and $1,200 for an extended warranty. Rachel, armed with Brey’s checklist, declined both. She also caught that the dealer had added a $300 “documentation fee” that was not disclosed beforehand. By negotiating that fee down to $100, she saved $2,700 upfront. When factoring in interest savings over a 60-month loan at 6.9%, her total savings exceeded $3,200.
“The dealer’s goal is to separate you from your money in the most profitable way possible,” Brey says. “But if you know the tricks, you can keep thousands of dollars in your pocket.” The key is to slow down, ask questions, and never feel pressured to sign on the spot. Bring a friend or a printout of the FTC’s “Shop Smart for a Car” guide. And remember: you can always walk away.
