Compare the buyer’s order line by line with a written out-the-door quote before you sign. Check the vehicle price, dealer-required fees, government charges, every add-on, and the financing totals—not just the monthly payment. If a charge is unfamiliar, ask what it is for, whether it is required, and whether you agreed to buy it. Don’t sign until the paperwork reflects the deal you chose.
What to check before signing a buyer’s order
A buyer’s order is a transaction document showing the vehicle and charges included in the proposed sale. It is not a substitute for checking the final sales contract and financing agreement. A charge can appear under an official-sounding name without being a government charge, and an add-on can be included in the payment even if you did not intend to buy it.

Your best point of comparison is a written out-the-door price for the specific used car. The Federal Trade Commission (FTC), in its consumer guidance Car Dealer Ads and Promotions: Know Before You Go, advises shoppers to get that price in writing before visiting and compare it with the dealer’s final paperwork. The quote helps reveal a late-added fee, a higher vehicle price, or a product that was not part of the original discussion.
- Confirm that the quote and buyer’s order refer to the same vehicle.
- Match the vehicle price and each charge against the quote.
- Separate dealer-required fees and government charges from optional products.
- Check the down payment, amount financed, APR, and total payment—not only the monthly payment.
- Ask for corrected documents if the order includes anything you did not approve.
These steps are a practical review, not a determination that a particular charge is legal or illegal. Requirements can vary by state and transaction. The FTC’s automobile pricing FAQs explain federal principles; they do not establish the rule for every state-specific fee or dispute.
#1 Best Overall
Get a written out-the-door quote first
Ask for the total on the specific car
Before going to the dealership, ask it to confirm that the used car is available and provide the total out-the-door price in writing. Specify the vehicle you mean so the quote cannot be confused with another car or a generic advertised offer. Ask that the quote include all dealer-required fees and identify any products already installed or proposed for the sale.
If the dealer gives you one combined figure, request a breakdown. You need to know the vehicle price, each required fee, any government charge, and the separate price of each optional add-on. An out-the-door figure is useful for comparing offers only when you can see what makes it up.
Compare offers on the same basis
When you compare two dealers, use the same vehicle if possible and put each quote into the same categories. A lower advertised price may not mean a lower final price if the buyer’s order adds fees or products. Likewise, a higher quote may include a product that you do not want and that should be considered separately.

| Compare | What to look for |
|---|---|
| Vehicle price | Does the buyer’s order show the same price as the written quote and the price you negotiated? |
| Dealer-required fees | Are they itemized, and do they match the quoted amount? FTC staff guidance says dealer-required fees must be included in the advertised price. |
| Government charges | Are they identified as government charges rather than described vaguely as dealer fees? The FTC’s automobile pricing FAQs treat required government charges differently from dealer-required fees. |
| Optional add-ons | Does each product have its own price and description? Did you choose to buy it? |
| Financing | Do the down payment, amount financed, APR, and total payment reflect the terms you discussed, rather than only a target monthly payment? |
| Final documents | Does the order and financing paperwork contain only the charges and products you agreed to, at the quoted prices? |
FTC staff’s Automobile Industry Pricing Transparency: FAQs state that dealer-required fees must be included in advertised prices, with required government charges treated as an exception. The same guidance describes deceptive practices such as implying an optional add-on is required, misstating its cost, or charging for an option the consumer did not agree to. An item’s presence on an order does not, by itself, tell you which category it belongs in; ask the dealer to explain it.
Read the buyer’s order line by line
Take the written quote and the buyer’s order together. Start at the top of the order and follow every line through the total. Do not skip a charge because it is small, appears near the bottom, or is included in a package. Make a note of unfamiliar wording and ask the salesperson to identify the product or service and its price.
- Match the car. Confirm the order identifies the vehicle you discussed and that the quoted price is for that same car.
- Match the vehicle price. Compare the order’s vehicle price with your written quote and any agreed negotiation.
- Classify every fee. Ask whether each charge is a dealer-required fee, a required government charge, or an optional product or service. Ask what the fee pays for and where it was included in the quote.
- Inspect packages and repeated items. Look for a bundle with no itemized price, the same service under two names, or an add-on that was not previously discussed.
- Check totals. Recalculate the listed charges against the amount due and compare that amount with the written out-the-door figure.
- Review financing separately. If you are financing, compare the down payment, amount financed, APR, and total payment information with the terms you agreed to.
- Stop on discrepancies. Ask the dealer to explain or remove any unapproved item and print or display corrected paperwork before you sign.
A useful question for any unfamiliar line is: “What is this fee for, and where was it included in the written out-the-door price?” Follow with: “Is it required, or can I decline it?” Ask for a clear answer and an itemized amount. Do not assume a charge is government-mandated because it appears on dealer paperwork or has an official-sounding label.

How to evaluate common used-car add-ons
The FTC defines add-ons as optional products or services offered by a dealer. Its consumer materials name GAP coverage, VIN etching, and rustproofing as examples; other products may be presented as service contracts, warranties, protection packages, or certification-related charges. The key is to consider each as a separate purchase rather than treating it as an automatic part of buying the car.
| Item | Questions to ask before agreeing |
|---|---|
| GAP insurance or agreement | What losses does it cover? What exclusions and limits apply? Does it apply to this vehicle and this financing arrangement? |
| Service contract or extended warranty | Which systems and repairs are covered? What is excluded? How long does coverage last, what is the deductible, and does it duplicate an existing warranty? |
| VIN etching | What exactly is done, what does it cost, and is the service optional? Was it already performed? |
| Rustproofing or paint and fabric protection | What work or tangible benefit is included? What is the price, and has the work already been done? |
| Dealer certification or reconditioning charge | What does the charge cover? Is it a required dealer charge, and was it included in the advertised price? |
| Other package or product | What specific product or service is being sold, what are its limits, what is the separate price, and did you affirmatively agree to buy it? |
FTC consumer advice warns that add-ons may be introduced late or included without a consumer’s discussion or approval. That makes the order—not just the earlier conversation—a necessary checkpoint. If a salesperson says the product is required, ask whether it is required by law, required by the lender, or simply required by the dealership. Ask for that distinction in plain language and compare it with the written quote before deciding.
For GAP products in particular, do not infer that the coverage suits your situation just because it is offered during financing. FTC enforcement materials describe allegations involving allegedly unsuitable GAP products. Those examples are reasons to ask about coverage and limitations, not proof that every GAP product is unsuitable.
For a service contract or extended warranty, compare the contract’s covered repairs, exclusions, duration, and deductible with any existing warranty. A product name alone does not tell you what it covers. Ask to review the written terms and price before it is added to the amount you finance.
For physical protection products such as etching, rustproofing, or paint and fabric protection, ask what was done or will be done, whether you can decline it, and whether it has already been performed. The FTC’s used-car and add-on guidance gives these as examples of products consumers should ask about, including what they receive and what it costs.

Do not treat every line labeled “fee” as the same kind of charge. A dealer-required fee is not automatically a government charge, and an official-sounding label does not establish that the government requires it. Ask the dealer to name the recipient or purpose, explain why the amount is charged, and show whether it was included in the advertised and written out-the-door prices.
The FTC’s current automobile pricing FAQs say a dealer-required fee must be included in the advertised price, while required government charges are handled differently. They also describe the FTC Act’s prohibition on deceptive practices, including misrepresenting an optional item as mandatory or charging for an option without agreement. These federal principles help frame the questions to ask; they do not answer every state-law question about a particular documentation, registration, or other charge.
The FTC’s broader Rule on Unfair or Deceptive Fees: Frequently Asked Questions discusses mandatory ancillary charges and optional items across industries. For a car purchase, use the vehicle-specific automobile pricing guidance for the auto-specific issue, and avoid assuming that a general example resolves a state or local requirement. If you need to know whether a fee is allowed in your state, check the relevant state consumer or motor-vehicle authority or seek state-specific legal advice.
FTC enforcement materials updated in 2026 describe cases involving allegations related to unwanted add-ons, used-car pricing, and charges for certification or government fees without consumer consent. An enforcement allegation is not a universal ruling about every similarly named fee. The facts and status of a particular case matter, as do the details of your own transaction.
Look beyond the monthly payment
A monthly payment can make an offer appear manageable while obscuring the amount financed or the total cost of the transaction. A product added to the contract can increase what you borrow and the payments over the loan, even if the monthly change seems small. The FTC’s Financing or Leasing a Car guidance advises consumers to consider total cost, review the sales contract and financing agreement, and get the terms in a printed or otherwise reviewable form.
Ask to see the amount financed and the full payment information, along with the down payment and APR. Compare those figures with the vehicle price and charges on the buyer’s order. If you are discussing a monthly payment, ask the dealer to show the complete terms that produce it rather than agreeing to a payment target without seeing what is included.
- Does the amount financed include an add-on you did not ask for?
- Does the down payment match what you agreed to pay?
- Does the APR match the financing terms presented to you?
- Can you see the total payment information, not just a monthly figure?
- Do the final sales and financing documents match each other and the buyer’s order?
Take time to review the full documents before signing. If the transaction is electronic, make sure you can see the actual terms, not merely where a signature is requested. An FTC alert about a 2024 enforcement matter described allegations that consumers at three Texas dealerships signed electronic devices showing signature locations but not the terms. That is a case-specific example, not evidence that every electronic signing process hides terms. The practical safeguard is to read the terms on screen or request a printed copy you can review.
What to do when the order does not match
If you find a charge or product you did not approve, pause the transaction. Ask the dealer to identify it, explain its price and status, and remove it if you do not want it. Request a corrected buyer’s order and recheck the totals and financing figures after the correction. Do not rely on a verbal promise that an item will be removed later.
- Point to the exact line. Name the charge or add-on and ask what it covers and whether it is required.
- State your choice plainly. If you do not want the product, say that you did not agree to buy it and want it removed.
- Request revised paperwork. Check that the new order shows the removal and that totals, amount financed, and payment terms have changed accordingly.
- Review the contract and financing agreement. Confirm that they contain only the agreed products and charges at the quoted prices.
- Keep copies. Obtain copies of the signed documents and retain the written quote and any revised order.
The FTC’s consumer video transcript, Understanding Car Add-ons – Consumer Tips, advises buyers to ensure that the contract lists only add-ons they agreed to, at the prices quoted. That is the final check: the paperwork should record your affirmative choices, not merely the dealer’s initial proposal.
What FTC examples do—and do not—show
In a 2024 alert concerning allegations against three Texas dealerships, the FTC said buyers reported that add-ons were placed in contracts secretly or presented as required. The agency said as many as 75% of buyers at those dealerships reported this experience. That figure is tied to allegations in that specific case; it is not a national estimate or a claim that 75% of all used-car buyers face hidden add-ons.
FTC automobile enforcement materials include allegations about add-ons, pricing, certification charges, and government-fee charges without consumer consent. They illustrate practices the agency has challenged, but an allegation or enforcement example should not be treated as a finding that every similar charge is unlawful. The FTC’s auto-pricing FAQs are more useful for the general federal pricing principles; state rules and transaction details still matter.
A 2023 FTC announcement described the CARS Rule as finalized and outlined offering-price and add-on disclosures. That announcement alone does not establish the rule’s present legal status, so this guide does not rely on it to claim the rule is currently in force. For this purchase, use the FTC’s current automobile pricing guidance and consult current, state-specific information for legal questions.
