Used-Car Inspection Checklist: What to Check Before Buying
Start with the documents: match the VIN, check the title and service history, and look up open recalls. At a dealership, read the Buyers Guide for warranty terms. Then walk around the car, ask to hear it start cold, and test-drive it if conditions allow. Write down what you notice and arrange an independent inspection before committing to the purchase. Ask for a written report and repair estimate.

Key findings
- A VIN mismatch or missing document needs an explanation before you move ahead with the purchase.
- The dealer's Buyers Guide describes warranty coverage. Get promised repairs and any changes to the deal in writing.
- A test drive helps you identify questions for a mechanic. It cannot establish everything about the car's condition.
- The FTC recommends an independent mechanical inspection even when a dealer has inspected or certified the car.
The evidence
| Check | Buying from a dealer | Buying from a private seller |
|---|---|---|
| Warranty information | Read the Buyers Guide and any warranty document | Ask what written terms apply; the FTC dealer form generally does not apply |
| Vehicle records | Request title, service and recall-repair records | Request the same records and match them to the car |
| Independent inspection | Arrange a mechanic you choose, including for a certified car | Arrange a mechanic you choose before committing |
| Promises about repairs | Have them reflected in the Buyers Guide and sale paperwork | Get the agreed work and terms in writing |
The details
- Match the documents. Check the VIN on the dashboard and door jamb against the title and registration. Look for salvage, rebuilt or flood branding. Review the available service history and use a vehicle-history report to check title and damage records. A history report can have gaps.
- Check recalls. Run the VIN yourself and ask for records of any claimed recall repairs. Our VIN-check guide explains why a zero result does not list completed work.
- Read the Buyers Guide. At a dealer, compare its warranty terms with the sale contract. For a dealer warranty, the form must identify covered systems, duration and the dealer's share of repair costs. The form's disclosures become part of the sale contract and override conflicting contract terms. Dealers may not make statements that contradict the form.
- Walk around the car. Note paint differences, uneven panel gaps and tire wear. Record what you see without assigning a cause. Check the lights and controls you can operate during the viewing.
- Ask for a cold start. If possible, arrange to see the car before the engine has been warmed up. Note any warning lights, difficult starting, noises or rough running and tell the mechanic when they occurred.
- Take a test drive. If the car can be driven and conditions allow, try local and highway roads. Note what happens during braking, steering and acceleration. Follow any instructions in an open recall notice before driving.
- Add model-specific questions. CarTold's Inspection Checklist uses the selected model year's recall campaigns and leading complaint categories. Bring relevant records to the inspection; they do not establish that the car has the reported problems.
- Book an independent inspection. Ask the mechanic what the inspection includes and what it costs. Request a written report with the VIN and estimates for needed repairs. If the seller will not allow an independent inspection, consider another car.
The FTC's Used Car Rule is 16 CFR Part 455. Its dealer definition covers a person or business selling or offering a used vehicle after selling or offering five or more used vehicles in the previous 12 months, with specified exceptions. Ordinary private sales generally fall outside this rule. That does not remove other rights or duties that may apply to the sale.
What to check before buying
- Before the visit: request the VIN, available service records and permission for an independent inspection. Ask whether the engine can be left cold for your arrival.
- At the car: match the paperwork, save the recall result and write down questions from the walk-around and drive.
- Before agreeing on repairs: get the mechanic's written findings and estimate. Use those details when discussing the sale terms.
- Before signing: make sure promised work and warranty terms appear in the paperwork you will keep.
Limitations
This is a buyer's checklist, not a mechanical diagnosis or a complete inspection procedure. The scope of a professional inspection varies, so ask what is included. CarTold does not have a named automotive specialist reviewing this guide. Federal dealer rules have exceptions, and state rules on warranties and "as is" sales vary; this guide does not resolve the legal terms of an individual sale.
Sources and methodology
The original regulatory source review was completed on 2026-08-10 using the official text of 16 CFR Part 455. The rule covers the dealer definition, Buyers Guide and contract requirements. The FTC's used-car buying guide supports the independent-inspection and written-report advice. CarTold's checklist uses model-year recall and complaint records.
