What to check before buying a used car

A good test drive is only part of the picture. Check the paperwork before you pay.

The answer in 2 lines. Before paying, verify the seller's authority to sell, match the vehicle identification number to the title, review title history and mileage records, check recalls and arrange an independent inspection. At a dealership, read the Buyers Guide and get every promise in writing. Private sales have different protections. Title transfers, inspections, emissions requirements and warranty rights vary by state.

Before you commit

Check ownership and title. Match the seller's identity and authority to the ownership documents. Use the official state motor vehicle directory, choose your state and find its buying and title-transfer instructions.
Check the history. Start with the official NMVTIS consumer page. Read what its reports cover and how to obtain one through an approved provider; compare the title, brand and mileage information with the seller's account.
Arrange an independent inspection. Have a mechanic of your choice inspect the car before purchase. The federal used-car buying tips recommend combining an inspection with history information.

Stop: danger

Unsafe to test-drive? Do not drive a car with an obvious tire, steering or braking problem. Arrange professional assessment instead.
A recall includes a do-not-drive warning? Follow the specific warning and repair instructions before driving.
The seller pressures you to drive despite a safety concern? Stop the viewing. You can leave without completing the purchase.

Work through the car and its records

Identity: compare the VIN on the car with the title and records. An unexplained mismatch needs resolution before payment.
Title: look for liens and brands such as salvage or rebuilt. A registration document alone does not answer every ownership question.
Mileage: compare the display with dated maintenance records and title information. Ask for an explanation of any inconsistency.
Condition: ask the inspecting mechanic to assess structural damage, corrosion, leaks, tires, brakes and warning lights, and provide a written repair estimate.
Maintenance: request invoices and ask what major work is due.

The California title guide illustrates the ownership, lienholder and branding information a title may contain. Use your own state's instructions to determine which documents are required for your transaction.

What not to do

Treating a clean history report as proof that a car has never been damaged.
Accepting a seller's inspection as a substitute for an independent assessment.
Signing blank documents or paperwork with unresolved VIN, price or mileage discrepancies.
Assuming you can return the car simply because you change your mind.

Dealer or private seller: read the actual terms

At a dealership, the FTC's used-car guide explains the Buyers Guide. Read whether the car is offered as is or with a warranty, what repairs are covered and who pays. Get a copy and make sure negotiated changes appear in writing.

A service contract is different from a warranty. Ask what it costs, what it excludes and whether it duplicates existing coverage. Do not rely on a salesperson's verbal promise that a problem will be fixed later.

Private sales generally involve different protections, and state law matters. The New York Attorney General's buying guide, for example, explains that private sales are outside that state's Used Car Lemon Law. Read the relevant state guidance before assuming a dealer warranty or lemon-law remedy applies to your purchase.

Before handing over money

Enter the VIN in the official safety-recall lookup. Read each result and the remedy instructions. An absence of displayed recalls does not replace a mechanical inspection or prove that every past repair was completed.

Ask for an itemized out-the-door price, including taxes, fees and optional products. If financing, compare the total cost and terms, not just the monthly payment. The Texas Attorney General's buying guidance explains why written terms and an independent inspection matter.

Confirm how any lien will be released, which signatures are needed and how you will submit the transfer. Use your state's instructions for registration, insurance, inspection and emissions requirements before arranging to drive the vehicle home.

Good to know

NMVTIS reports focus on title-related history; they are not complete maintenance or repair records. Read the limitations on the official consumer page linked above.
If the seller refuses a reasonable independent inspection, consider another car.
Keep the advertisement, signed agreement, payment record, inspection and disclosures together. They help establish what was represented and agreed.

Avery likes a used sedan and its smooth test drive. Before paying, Avery checks the title history and learns it carries a rebuilt brand. An independent mechanic identifies repairs needing further evaluation. Avery pauses the purchase instead of relying on the seller's assurance that the car is fine.
