A used car decision needs more than an attractive monthly payment. Check the written price, the vehicle’s condition, the dealer’s Buyers Guide, recall information and the full financing terms before signing. The FTC and CFPB provide official guidance on these separate parts of the transaction. This checklist helps you organize the questions without recommending a particular vehicle, lender or loan.

Get the used car price in writing
The FTC recommends asking dealers for an out-the-door price before a visit. That makes it easier to see whether an advertised offer includes the charges that matter to the final transaction. Keep the quote tied to the specific vehicle and VIN.
Compare the written itemization rather than only a large price printed in an advertisement. If the final paperwork differs, ask what changed and why. Do not assume a verbal explanation has updated the document you are being asked to sign.
A useful private note lists the vehicle, quoted amount, included items and date. It helps you compare offers without mixing a quote for one car with financing or equipment from another.
2. Read the dealer’s Buyers Guide
The FTC explains that the Buyers Guide identifies whether a covered dealer vehicle is sold as is or with a warranty, among other information. Read the actual guide for the car, including the stated repair-cost treatment if a warranty is offered.
Keep written promises consistent across the documents. A reassuring conversation about future repairs does not automatically change the terms printed in the guide or contract. Ask for an explanation and an appropriate written record before proceeding.
State law and the transaction’s details can affect rights and obligations. This general guide does not determine the legal effect of a particular as-is sale or replace advice about a dispute.
3. Arrange an independent mechanical inspection
The FTC says a vehicle history report is not a substitute for an independent inspection. A history report, a dealer’s certification and a mechanical examination provide different information. Check what the inspection covers and obtain a written report.
A hypothetical car can have an appealing service history while still needing an expensive repair that a current inspection identifies. Another can have a clean-looking exterior without revealing its mechanical condition. The useful evidence is what was examined and found.
If a seller will not permit the inspection process you need, consider what uncertainty remains before making a decision. This article does not diagnose a car from a listing or promise that any inspection eliminates every future repair.
4. Check recalls with the actual VIN
Use NHTSA’s official lookup for unrepaired recalls and read its stated limitations. A model-level article is not the same as a VIN-specific result. A zero-open-recall result also does not establish that the vehicle has no mechanical problems.
If a recall applies, review the manufacturer’s notice and any interim safety instruction. Ask about the remedy and documentation. Do not assume the general condition inspection and recall status are interchangeable records.
Keep the date of the search and any completion record with your purchase notes. New campaigns can arise later, so a one-time lookup is not a permanent guarantee.
5. Compare the full financing offer
The CFPB advises comparing the amount financed, APR and interest rate, loan length and monthly payment. A longer term may lower the monthly amount while increasing interest paid over the life of the loan. The monthly figure alone does not describe the whole cost.
Here is an invented arithmetic illustration, not a loan quote. Payments of $400 for 60 months total $24,000, while $350 for 84 months total $29,400. Those totals exclude any separate down payment and assume the stated payments occur throughout. The lower monthly figure produces the larger payment total in this example.
Actual comparisons require the real disclosures and all relevant terms. Do not treat the example’s amounts as current market rates, an approval promise or advice about what a particular household can afford.
6. Separate optional add-ons from the core deal
CFPB guidance explains that products such as extended warranties, GAP insurance and credit insurance are generally optional in an auto-loan transaction. If an add-on is financed, it can increase the amount borrowed and the payments.
Ask what the product covers, its price and the applicable terms before accepting it. A service contract, a manufacturer warranty and an insurance product can have different conditions. A familiar label is not enough to compare them.
If the paperwork includes something you did not agree to buy, ask for an explanation and corrected documents before signing. This article does not assess whether a specific product is suitable for your circumstances.
7. Review the final documents at the same scope
Before signing, compare the final vehicle identity, itemized price, trade-in treatment if any, amount financed and add-ons with the offer you reviewed. Check that the documents describe the same transaction and that blanks or unexplained changes are resolved.
Keep copies of the documents and the inspection and recall records. If a problem later arises, a dated record of what was promised and agreed is more useful than an approximate recollection of a conversation.
A practical shopping folder can contain one page of questions plus the supporting records. That keeps the decision organized without requiring a public post of your credit application, identity documents or financial information.
For a 2027 purchase, revisit current FTC, CFPB and NHTSA guidance and use actual offers available at that time. This 2026 review supplies a reading method, not a forecast of prices, borrowing costs or the reliability of a particular car.
Frequently asked questions
Is a low monthly payment enough to compare used car loans?
No. Compare the amount financed, APR, term and total payment obligations using the actual disclosures.
Does a vehicle history report replace an inspection?
No. The FTC says a history report is not a substitute for an independent mechanical inspection.
What does the Buyers Guide tell me?
For covered dealer sales, it identifies warranty or as-is information and other important details about the vehicle and repair-cost terms.
Are extended warranties and GAP products always required?
CFPB guidance says these products are generally optional in auto-loan transactions. Read the actual terms and ask about any claim that a product is required.
Does no open recall mean a used car is mechanically sound?
No. A recall lookup has a specific scope and does not replace a condition inspection.
