The number in the ad and the number on the final paperwork are rarely the same. The gap between them is where dealer fees, add-ons, and financing terms quietly do their work — and federal protection here is weaker than most buyers assume.
Where the extra cost actually comes from
- Documentation ("doc") fees — a charge for paperwork processing, varying enormously by dealer and state, from under $100 to several hundred dollars
- Add-on products — extended warranties, paint protection, VIN etching, gap insurance — often presented as routine steps in the finance office rather than optional purchases
- Financing markup — a dealer arranging your loan can add a margin on top of the actual rate the lender offered
- Taxes, registration, and title fees — legitimate, but sometimes bundled in ways that make comparison between dealers difficult
Why the federal "junk fees" crackdown isn't actually in effect
The FTC's Combating Auto Retail Scams (CARS) Rule would have required dealers to advertise one honest, all-in price and banned deceptive add-on tactics. It never took effect: the Fifth Circuit Court of Appeals vacated it on January 27, 2025, finding the FTC skipped a required procedural step, and the FTC formally withdrew it from the Code of Federal Regulations on February 12, 2026. As of now, there's no sign the agency is restarting that specific rulemaking process.
What's still illegal, even without the CARS Rule
Section 5 of the FTC Act — in force since 1914 — separately prohibits unfair or deceptive practices, and the FTC has continued using it against dealers: a $20 million settlement in 2024, and warning letters sent to 97 dealer groups in March 2026. At an April 2026 industry webinar, the FTC stated directly that mandatory dealer-imposed fees like doc fees must be included in the most prominently advertised price in all 50 states — state doc-fee statutes don't override this federal requirement.
States are filling the gap the CARS Rule left
With the federal rule gone, states have moved on their own: Massachusetts issued a broad "Junk Fee Rule" in March 2025 requiring the total price to be disclosed clearly and displayed more prominently than any other pricing information. California's own CARS Act was pending before the state Assembly with a proposed effective date of October 1, 2026. Check whether your specific state has passed its own version, since protection now varies significantly by location rather than being uniform nationally.
How to actually get the real price before you commit
- Ask directly for the "out-the-door" price in writing before discussing financing or trade-in value — this should include every fee, tax, and charge.
- Ask what the doc fee specifically covers, and whether it's negotiable — this varies enormously by dealer even within the same state.
- Decline add-on products in the finance office explicitly and in writing if you don't want them — don't assume declining verbally is enough.
- Get your own financing pre-approved before visiting the dealer, so you have a real number to compare their financing offer against.
- Compare the total price across multiple dealers for the same or similar vehicle, not just the advertised sticker price.
What this means practically
- The federal CARS Rule that would have mandated all-in pricing is not in effect and was formally withdrawn in February 2026 — don't assume this specific federal protection applies.
- The FTC is still actively enforcing against deceptive pricing under the older Section 5 of the FTC Act, including real fines and warning letters in 2026.
- Some states have passed their own junk-fee or all-in pricing laws — check your specific state's current rules rather than assuming federal or no protection applies uniformly.
- Getting the full out-the-door price in writing before discussing financing remains your single best protection regardless of which rules currently apply.
