What this scam usually looks like

In this scam, a seller winds back or alters a used car's odometer to show lower mileage, making the vehicle seem less worn and worth more, hiding wear and inflating the price.

Marketplace scams target both buyers and sellers on platforms like Facebook Marketplace and classified listings. Fraudsters fake payments, send bogus "buyer protection" emails, push deals off-platform, or use overpayment tricks to make you ship goods or send money for nothing.

The single clearest warning sign to remember is this: A used car's low mileage does not match its condition or service history. Check mileage against service records and official history before buying.

Example message pattern

Example pattern, not a real report
Example pattern: A well-worn car shows surprisingly low mileage, with a service history that has gaps or mileage entries that do not add up.

This is a fictional, anonymised example used to illustrate the pattern. It is not a verified real message, and any names are used only to show how the scam typically reads.

Why this is a red flag: A used car's low mileage does not match its condition or service history.

Red flags to watch for

  • Mileage that seems low for the car's age and wear
  • Gaps or inconsistencies in the service history
  • Worn pedals, seats, or steering wheel versus low mileage
  • A seller reluctant to share full history
  • Pressure to buy quickly

What to do

  • Check mileage against service records and official mileage history
  • Look for wear that matches the displayed mileage
  • Get an independent inspection before buying
  • Verify the vehicle's history through official checks

If you already clicked or replied

  • If you suspect clocking, get an inspection and history check
  • Report odometer fraud to the relevant authority
  • Keep the advert, records, and any evidence
  • Seek advice on your consumer rights

What not to do

  • Do not rely on the displayed mileage alone
  • Do not skip a history and service-record check
  • Do not let pressure rush your inspection

Frequently asked questions

What is car clocking?
It is winding back or altering a car's odometer to show lower mileage, making it appear less used so the seller can charge more.
How do I check true mileage?
Compare the odometer against service records and official mileage history, look for wear consistent with the mileage, and get an independent inspection.
I think my car was clocked. What now?
Get an inspection and history check, report the fraud to the relevant authority, keep your evidence, and seek advice on your rights.
Why is clocking hard to spot?
Modern odometers can be altered electronically, so the display alone is not proof. History checks and physical wear are better indicators.
