Use the checklist in the correct order
Do the inexpensive checks first. Review the listing and question the seller before travelling. Verify ownership and records before paying for inspections. Inspect, test-drive, and obtain professional advice before negotiating the final price.
Before contacting the seller
- Confirm that the vehicle type, age, mileage, fuel type, and size fit your needs.
- Compare the asking price with genuinely similar vehicles.
- Read the full listing for missing facts, contradictions, and vague claims.
- Save a copy of the advertisement and photographs.
- List every important question the advertisement does not answer.
Questions to answer before viewing
- Is the seller the owner or an authorised dealer?
- Why is the vehicle being sold?
- What faults and warning lights are currently present?
- What repairs or maintenance are due soon?
- Are service invoices and inspection documents available?
- Has the vehicle suffered damage or major repairs?
- Will the seller allow an independent inspection?
At the vehicle
Exterior and identity
Match the identification number, inspect panel gaps, paint, glass, tyres, lamps, corrosion, and signs of repair.
Interior and controls
Test warning lights, climate control, windows, locks, seats, infotainment, cameras, and safety equipment.
- Start the engine cold when possible.
- Look for leaks, smoke, unstable idle, and unusual noises.
- Check fluid condition only where safe and appropriate.
- Compare interior wear with the stated age and mileage.
During and after the test drive
- Test low-speed and normal-road driving.
- Observe steering, braking, acceleration, and transmission behaviour.
- Listen for suspension, bearing, or drivetrain noises.
- Watch for warning lights, vibration, overheating, or unusual smells.
- Recheck for leaks after the drive.
- Write down symptoms rather than guessing the cause.
Before paying
- Review the independent inspection report.
- Verify applicable ownership, finance, theft, write-off, and registration records.
- Calculate immediate maintenance and repair exposure.
- Agree the price and included items in writing.
- Complete the correct local transfer process.
- Keep the advertisement, messages, receipt, and payment evidence.

Scan a used-car listingFrequently asked questions
What is the most important used-car buying check?
No single check is enough. The most important process is to compare the listing, seller answers, documents, physical condition, test drive, and independent inspection for consistency.
Can I use this checklist for a dealer and a private seller?
Yes, but the documents, consumer protections, fees, and seller obligations may differ. Verify the rules that apply in the vehicle's jurisdiction.
Should I pay a deposit before seeing the car?
Avoid paying a deposit until the seller, vehicle, terms, and refund conditions are clear. Remote transactions require additional verification and payment safeguards.
What should I do if the seller refuses an inspection?
Treat refusal as increased risk. A seller may have practical reasons, but you should not proceed as though the vehicle's condition has been independently confirmed.
