How to Avoid Fraud When Buying a Used Car

The used car market is full of dishonest sellers — from clocked mileage to hidden accident damage. Every year thousands of buyers lose money to unscrupulous traders. Here is how to recognise the scams and protect yourself.

The Most Common Fraud Schemes

1. Odometer Clocking (Mileage Fraud)

What it is: Reducing the reading shown on the dashboard.

Scale: Up to 30% of used cars on the market may have clocked mileage.

How it works:

• Specialist equipment "winds back" the odometer
• A car with 250,000 km becomes 120,000 km
• The price jumps by 3,000–5,000 €

2. Hidden Accident Damage

What it is: A car repaired after an accident is sold as "no accident history".

Risks:

• Weakened bodyshell (safety implications)
• Hidden damage that causes future failures
• Inflated purchase price

3. Title Washing (Document Laundering)

What it is: A car with "salvage" or "total loss" status from the USA or elsewhere is re-registered in Europe with a clean title.

How it works:

• Bought cheaply at a US auction
• Shipped to Europe
• Re-registered as a normal car
• Sold as "imported from Germany"

4. VIN Cloning

What it is: The VIN number is changed so that the car appears to be a different (clean) example.

Risks:

• You could unknowingly buy a stolen vehicle
• Registration problems
• Potential criminal liability for the buyer

5. Precision Clocking

What it is: Mileage is set to a specific number designed to match the service history.

How it works:

• The fraudster knows the last service record shows 80,000 km
• Odometer is set to 95,000 km (looks plausible)
• Buyer sees a "normal" ownership history
• Nothing appears suspicious at first glance

How to Spot Clocked Mileage

Physical Signs

Steering wheel and gear lever:

• Heavy wear = high mileage
• If the claimed mileage is low but the steering wheel is polished — CLOCKED

Pedals:

• Rubber inserts worn through
• Metal visible on brake or clutch pedal

Seats:

• Driver's seat excessively worn or sagging
• Side bolsters worn on driver's side

Door handles and buttons:

• Faded, worn lettering
• Plastic worn smooth or shiny

Mileage vs Condition Mismatches

Document Checks

Service book:

• Are entries consistent and sequential?
• Any unexplained gaps or backwards jumps in mileage?
• Do the stamps look genuine?

VIN report:

• carVertical, AutoDNA or similar services
• Shows mileage history across multiple registration points
• If mileage "jumped backwards" at any point — CLOCKED

MOT / Inspection History

MOT records:

• Every MOT records the mileage at time of test
• If the current odometer shows LESS than a previous MOT — 100% clocked
• Most countries' vehicle registration databases are publicly searchable by VIN

Signs of Hidden Accident Damage

Bodywork Inspection

Colour mismatches:

• View the car from the side at low angle
• Repainted panels have a slightly different texture or sheen
• "Orange peel" effect on repainted sections

Panel gaps:

• Between doors and body
• Between bonnet and wings
• Uneven gaps = accident + poor repair

Magnet test:

• Hold a magnet against the bodywork
• If it doesn't attract strongly — there is filler (repaired area)

Glass

Date codes:

• Every piece of glass has a manufacture date
• All glass should be of similar age
• If the front windscreen is newer — why was it replaced?

Under the Car

Chassis rails:

• Any bending, straightening marks, or fresh welding?
• Is the underfloor symmetric (compare both sides)?

Underfloor:

• Fresh underseal can conceal recent repair work
• Look for "new" bare metal sections

Engine Bay

VIN labels:

• Any signs of replacement or tampering?
• Are the adhesive labels old and original?

Paintwork inside the engine bay:

• Should match the exterior
• Repainted inner wings or firewall = major accident repair

Red Flags in Advertisements

Suspicious Listings

Price too good to be true:

• 20%+ below market value = something is wrong
• "Need the money urgently, hence cheap" — a classic scammer phrase

Vague description:

• "Mechanically sound" — tells you nothing
• "Don't know the history" — may be true, but also convenient

Too few photos:

• Only 2–3 exterior photos = hiding something
• No interior, boot, or engine bay photos

Pressure and urgency:

• "Have to sell today"
• "Another buyer is coming in an hour"

Seller Behaviour

Reluctance to show or allow:

• Refuses a test drive
• Won't show documents
• Wants to rush the transaction

Inconsistencies:

• Selling on behalf of "a friend" or "relative" (not the registered owner)
• Doesn't know basic facts about the car
• Story changes between conversations

Payment pressure:

• Asks for a deposit before you've inspected the car
• Offers a "special price" for cash only
• Wants the deal concluded immediately

How to Protect Yourself

Before the Meeting

1. VIN report — ALWAYS:

• carVertical, AutoDNA or similar
• Cost: 10–25 € (can save thousands)
• Shows mileage history, accident flags, theft records, title status

2. Google the seller:

• Search their phone number and name
• Has anyone warned about this seller online?

3. Check the listing history:

• Has this car been listed before?
• Has the mileage dropped between listings?

During the Inspection

1. Document verification:

• VIN matches on the dashboard, doorframe sticker, V5/registration document, and under the bonnet?
• Seller is the registered owner?
• Service history is consistent and logical?

2. Physical inspection:

• Use a checklist (see below)
• Photograph everything
• Don't feel embarrassed to take your time

3. Test drive:

• ESSENTIAL — do not skip this
• You should drive, not just be a passenger
• Test in different modes: city, faster road, sharp corners, emergency stop

Professional Help

Independent mechanic inspection:

• Cost: 50–100 €
• Professional assessment with diagnostic scan
• Strongly recommended for any car over 5,000 €

Paint thickness gauge / bodywork specialist:

• Measures paint thickness to detect filler or respray
• Checks chassis geometry
• Recommended for cars over 15,000 €

What to Do If You've Been Defrauded

Legal Options

Consumer protection (if buying from a dealer):

• Statutory rights apply — you can claim for misrepresentation
• Requires formal complaint to the seller first

Police:

• If clear fraud occurred (clocked mileage, concealed write-off)
• Odometer fraud is a criminal offence in most jurisdictions

Civil court:

• Civil claim against the seller
• Evidence will be required — keep all documentation

Prevention Is Always Better

It is always cheaper to avoid fraud than to pursue it through the courts.

Checklist

Before the meeting:

• VIN report checked
• Market value researched
• Seller's contact details verified

Documents:

• VIN matches on all points (dash, door, V5/registration, engine bay)
• Registration document matches seller
• Service history is logical and consistent
• MOT/inspection is current

Physical inspection:

• Mileage vs condition checked for consistency
• Bodywork checked for accident signs
• Paint colour consistent across all panels
• Panel gaps uniform

Test drive:

• Completed
• No unusual noises
• Engine runs normally
• All electrics working

FAQ

Can you be 100% certain the mileage is genuine?

Never with 100% certainty. But a VIN report + physical inspection + MOT history together reveal most cases. If the MOT/inspection records show a HIGHER mileage than the odometer now — it is 100% clocked.

Is odometer fraud a criminal offence?

Yes, in most countries it constitutes fraud or misrepresentation under criminal law. However, proving it and pursuing prosecution requires evidence — which is why documentation before purchase is so important.

Is it worth buying a high-mileage car with genuine history?

YES. A genuine 200,000 km car with full documented history is far preferable to a suspicious 100,000 km car. Honesty matters more than the number.

How much does a VIN report cost?

10–25 € depending on the provider and depth of data. It is the best single investment you can make before buying a used car.

Conclusions

Fraudsters exist — but protecting yourself is entirely possible:

The essential rules:

• VIN report — ALWAYS before you travel to see it
• Physical inspection — thorough, unhurried
• Trust your instincts — if something feels wrong, it probably is
• Don't be rushed — fraudsters rely on pressure

Red flags = walk away:

• Price too good to be true
• Seller is pushing for a quick decision
• Document inconsistencies
• Refuses inspection or test drive

It is always better to miss a "great deal" than to buy a problem.
