The 10 Most Common Used Car Scams

1. Outstanding Finance (Cost: Full price of car)

The seller owes money on a PCP, HP, or secured loan. They sell the car and pocket the cash, leaving the finance unpaid. The finance company repossesses the car from you. This is the most common and most expensive scam, affecting an estimated 1 in 3 used cars.

How to avoid it: Run the £4.99 premium check on CarCostCheck. It queries the Experian database for any finance registered against the vehicle.

2. Mileage Clocking (Cost: £2,000-5,000 overpayment)

The odometer is wound back to show fewer miles, inflating the car's value. An estimated 2.5 million clocked cars are on UK roads. The tools to clock a digital odometer cost under £30 and the process takes minutes.

How to avoid it: The free CarCostCheck report plots every MOT mileage reading on a timeline. Any drop in mileage between tests is definitive proof of clocking.

3. Undisclosed Write-Off (Cost: £1,000-5,000 overpayment)

The car was previously written off by an insurance company after an accident. It has been repaired and relisted without disclosing the write-off history. You pay clean-car prices for a vehicle worth 20-50% less.

How to avoid it: The £4.99 premium check shows the full write-off history including the exact category (A, B, N, or S).

4. Stolen Vehicle (Cost: Full price of car)

The car has been stolen and is being sold with cloned or altered identity. If the police trace the vehicle, they will seize it. You lose both the car and your money with no compensation.

How to avoid it: The £4.99 premium check queries the Police National Computer for theft records.

5. Deposit Scam (Cost: £100-500 deposit)

The seller asks for a deposit to "hold" the car before you view it. The listing may use stolen photos of a real car that the scammer does not own. Once the deposit is sent, the seller disappears.

How to avoid it: Never pay a deposit before viewing a car in person. No legitimate seller needs a deposit from someone who is coming to view the car.

6. Cut and Shut (Cost: Full price + safety risk)

Two written-off cars are welded together to create one apparently complete vehicle. The weld points are structural weaknesses that can fail in a collision. This is rare but extremely dangerous.

How to avoid it: Check the VIN matches across all plates on the car (dashboard, door frame, engine bay). The premium check verifies the VIN against DVLA records. A professional inspection can identify weld points.

7. Fake Service History (Cost: £1,000-3,000 in unexpected repairs)

The seller provides a forged service book with fake stamps to make the car appear well-maintained. The car may have missed critical services (timing belt, major service) that lead to expensive failures.

How to avoid it: Cross-reference the service book mileage entries with the MOT mileage readings on CarCostCheck. Inconsistencies suggest tampering. Call the garages stamped in the book to verify the work was done.

8. Curbing (Illegal Dealer Posing as Private Seller)

A car dealer sells through private listings to avoid giving buyer protections under the Consumer Rights Act. They typically sell multiple cars but present each as a personal sale.

How to avoid it: Search the seller's phone number and name online. If they appear in multiple listings for different cars, they are likely a dealer. Check the V5C to see how long they have owned the car. Frequent keeper changes can indicate a trade seller.

9. Misrepresented Specification

The car is described as a higher specification than it actually is. "Full leather" that is actually half-leather, "panoramic roof" that is a standard sunroof, or an engine size that does not match the listing.

How to avoid it: The free CarCostCheck report shows the car's actual specification as recorded by the DVLA, including engine size, fuel type, and body type. Compare this with the listing claims.

10. Outstanding Recalls

The car has an open safety recall that the seller has not addressed. While not always fraudulent, this can be a safety issue and a negotiation point.

How to avoid it: The free CarCostCheck report checks the DVSA database for outstanding recalls on the specific vehicle.

The free check catches 3 of 10 scams. The £4.99 premium check catches 8 of 10. The only scams it cannot detect are deposit fraud (do not pay deposits) and curbing (research the seller independently). For £4.99, that is the best protection available.

Frequently Asked Questions

What Makes CarCostCheck Different

CarCostCheck is not just a cheaper version of HPI. It is a fundamentally better product that happens to cost 75% less. Here is what you get that HPI does not offer at any price:

  • Real-time market valuation from £2.99, powered by over 650,000 live UK dealer listings. See what your car is actually worth in your local area, how quickly similar cars sell, and how the price compares nationally.
  • Estimated vehicle lifespan: Our AI model analyses over 100 million data points to predict how many years the car has left and the probability of it being on the road in 12 months.
  • Insurance costs by age: See estimated annual premiums for drivers aged 20, 30, 40, and 50. Budget before you buy.
  • Running cost breakdown: Annual fuel, road tax, MOT, predicted repairs, and total cost per month. All calculated for this specific car.
  • Health score (0-100): A single number that tells you the overall condition of the vehicle based on MOT history, advisory patterns, mileage consistency, and maintenance trends.
  • Common faults: Known issues for this exact make and model, drawn from real MOT failure data across thousands of vehicles.
  • 12 free checks: Full MOT history, mileage verification, reliability score, running costs, fuel costs, insurance group, red flag alerts, common faults, recall check, ULEZ compliance, and more. All before you pay a penny.

The premium history check (£4.99) uses the same Experian database as HPI, AA, and RAC. You get identical stolen, finance, and write-off data. The complete bundle (history + valuation) is £6.99, still 65% cheaper than HPI's basic check.
