Ask these questions before paying for a used car in the United States. The aim is to get a document, a way to check the answer and a clear next step when the answer is incomplete. A seller can be friendly and still be mistaken about a title, warranty or repair.

Prepare the questions before visiting. Write down the advertised year, make, model, VIN if supplied, asking price and seller's name. For a dealer, request the out-the-door price in writing before traveling; the FTC recommends this so you can compare the actual total and spot fees or add-ons introduced later. Set your budget for insurance, registration, immediate repairs and the purchase itself. A low monthly payment tells you little about the total cost if financing runs for a long period.

Who can transfer this vehicle?

Ask: "Is the title in your name, and is there a lien?" Compare the VIN on the car with the title and other sale paperwork. Ask your state motor-vehicle agency how that title must be transferred. If a seller promises to produce the title later, wait. For a title brand or mileage question, a consumer-access NMVTIS report may help, within its stated limits.

Look at the VIN in more than one place on the vehicle and paperwork, using the locations the vehicle maker or state agency identifies. A single transposed character can make a report or title check apply to another vehicle. Ask which state issued the current title and whether any lien release document is needed. The NMVTIS explanation describes title and brand information it may contain, but it does not supply a complete repair history or replace the state agency's transfer rules. If the seller cannot explain a mismatch, do not solve it by accepting an oral promise.

What was repaired, and what still needs work?

Ask why the owner is selling and for dates, mileage and invoices for recent service, tires, brakes and major repairs. Ask whether any warning message is present and what diagnosis was performed. A story about a "small sensor" is not a diagnosis. Use the VIN in the NHTSA recall lookup and ask the manufacturer about open campaigns when needed; an empty result does not certify the vehicle's whole history.

Compare each invoice with the odometer reading and the seller's account. A receipt for new tires tells you what was purchased, while the tires on the car tell you what is fitted today. Ask which repairs remain unfinished and whether the vehicle is safe and legal to drive to an inspection. The NHTSA search addresses unrepaired recalls reported for the VIN; it is not a certificate that the brakes, engine or body are trouble-free. Keep the service paperwork, history report and your own observations as different pieces of evidence.

Ask for a normal test drive and an independent inspection before money changes hands. If the car cannot leave the dealer lot for insurance reasons, ask whether an independent mobile inspector can examine it there or whether the dealer will take it to a shop you choose. The FTC says to consider another dealer if independent inspection is refused. Do not turn that refusal into a negotiation over price alone.

Arrange the inspection with a mechanic you choose and ask for a written report tied to the car's VIN. The FTC notes that a vehicle-history report and a dealer's own inspection do not replace an independent mechanical inspection. Ask the inspector to identify safety concerns, likely repairs and estimated costs separately from cosmetic wear. Then compare the report with the seller's statements. A finding may change the price you are willing to pay, require repair before sale or end the deal; decide after seeing it, not while the seller is pressing for a deposit.

What exactly will I pay and receive?

For a dealer sale, request the full out-the-door price in writing, with taxes, dealer fees, optional add-ons and financing terms separated. Read the FTC Buyers Guide and the warranty or service-contract documents. The Guide states whether the dealer offers a warranty or sells the car "as is"; state rules can add protections or conditions. For a private sale, ask about known faults and get any promise to fix them in writing as part of the agreement.

At the desk, compare the final contract line by line with the written quote. Ask what each add-on is, what it costs and whether it is optional. If financing, compare the annual percentage rate, number of payments, total of payments and down payment, not only the monthly figure. The FTC Buyers Guide should match what the dealer says about warranty coverage. A salesperson's description of a repair promise is not enough if the written contract says something else. Take time to read the documents before signing.

Write down three things before deciding: the verified title and VIN, the independent inspector's findings, and the total price with immediate repairs. If one is missing, the question is still open. The viewing checklist helps record what you see; these questions identify what the seller must explain.

Keep copies of the quote, report, Buyers Guide where applicable and any written promises. If the seller changes the vehicle, price or terms, revisit the checks for that exact car. A good answer is one you can verify in the documents and with the appropriate agency or inspector. You can leave without paying when an important answer remains unresolved; the ability to compare another car is part of the buyer's protection.
