The state of the UK used car market in 2025
The UK used car market sold approximately 7.8 million vehicles in 2025, making it one of the most active secondhand car markets in Europe. For buyers, that volume represents a wealth of choice. But it also means the market is large enough to hide a significant number of vehicles with problematic histories, from fraudulent mileage readings to hidden finance agreements and cars that were stolen and disguised before being sold on.
This report draws on DVLA data, police statistics, vehicle history check data from millions of queries, and industry research to give a complete picture of the four main risks facing used car buyers in the UK in 2025. Our aim is to give buyers, motoring journalists, insurers, and consumer advocates the clearest possible view of what is happening in the market.
Mileage fraud (car clocking)
estimated to be sold with falsified mileage in the UK every year
Car clocking affects approximately 2.1% of all used cars changing hands in the UK each quarter. The practice involves deliberately winding back the odometer to make a vehicle appear to have covered fewer miles, inflating its perceived value and concealing wear and tear. Buyers of clocked cars overpay by an average of 48.8% compared to what the vehicle is actually worth at its true mileage.
The technology required to alter a digital odometer is increasingly accessible and inexpensive, which has made enforcement harder. Some services openly offer "mileage correction" for legitimate reasons, and these are exploited by sellers with dishonest intent. The average UK fleet also got younger between 2023 and 2024, falling from 12.5 years to 11.8 years old, which means higher-value newer cars are increasingly being targeted.
| Model | % of Checks Showing Fraud | Avg. Miles Rolled Back |
|---|---|---|
| Nissan Qashqai | 9.7% | 15,490 |
| Volvo XC60 | 8.4% | 18,317 |
| Audi A6 | 8.4% | 28,000 |
| Mercedes-Benz E-Class | 8.3% | 31,500 |
| Volkswagen Touareg | 8.2% | 19,500 |
| BMW 5 Series | 7.7% | 24,200 |
| Land Rover Defender | 3.0% | 59,201 |

Outstanding finance
checked carry outstanding finance, meaning the seller does not fully own the vehicle
The UK car finance market reached nearly £39 billion in 2024, with over six million consumers actively funding a car purchase. More than 80% of new private car sales use PCP or HP agreements. When these vehicles enter the used market, the underlying debt frequently remains active. The finance company, not the seller, holds legal title until every payment is cleared.
If you purchase a car with undisclosed outstanding finance, the lender can repossess it from you regardless of what you paid. While Section 27 of the Hire Purchase Act 1964 offers some protection for good-faith private buyers, it does not apply to dealer purchases and is not an automatic guarantee. The proportion of cars carrying finance has risen steadily in line with the dominance of PCP agreements in the new car market over the past decade.
Insurance write-offs
checked have been written off by an insurer at some point in their history
When an insurer declares a car a total loss, it must register the write-off with national databases. Around 4% of all used cars checked carry a write-off marker. Category S (structural damage, repairable) and Category N (non-structural damage, repairable) cars can legitimately return to the road after repair, but the quality of that repair determines whether the car is safe and sound — and that quality varies enormously.
Undisclosed write-off history is a serious problem. A vehicle purchased cheaply at a salvage auction, repaired to a minimal standard, and then sold without disclosure represents a genuine safety risk in addition to a financial one. The write-off category and date will always appear on a comprehensive vehicle history check, even if the seller has not mentioned it.
Stolen vehicles
in the UK in 2025, equivalent to one every 10 minutes around the clock
Approximately 60,900 cars were stolen in the UK during 2025, a rise of around 12.8% on 2024 figures. London accounted for more than a quarter of these thefts, with the Metropolitan Police recording 16,907 vehicle thefts in the year. While around 44.9% of stolen vehicles were recovered, a significant proportion were broken for parts or had their identities altered before entering the used car market.
The most common method for premium and hybrid models is relay theft targeting keyless entry systems. Organised crime groups are increasingly targeting newer hybrid models — the Toyota C-HR, Toyota RAV4, and Lexus NX all featured prominently in 2025 theft data — because the powertrain components carry high resale value on the secondhand parts market.
| Model | Thefts in 2025 (est.) | Primary Method |
|---|---|---|
| Ford Fiesta | 3,511 | Parts demand |
| Volkswagen Golf | ~1,650 | Relay theft |
| Ford Focus | ~1,600 | Parts demand |
| Toyota RAV4 | 1,348 | Relay theft |
| Toyota C-HR | 967 | Relay theft |
| Lexus NX | 951 | Relay theft |

Which models carry risk across multiple categories?
Some models appear in the data across more than one risk category. The table below identifies models where buyers should exercise extra caution because the vehicle carries elevated risk in at least two of the four areas covered by this report.
UK's most clocked car at 9.7% fraud rate. Also one of the most finance-purchased models nationally.
Highest average mileage rollback of any model. Also targeted by organised theft groups for high-value parts.
Consistently in top-ten clocked models. Also targeted for OBD port key programming theft.
Fourth most stolen model in 2025. Also carried a significant proportion of write-off markers in checks.
Third most stolen model. One of the most finance-purchased used models in the UK, raising outstanding balance risk.
High clocking rate driven by strong mileage-linked residual values. Also appears regularly in write-off data for older examples.
Key findings: what this report tells us
The UK used car market remains an attractive environment for buyers — but also for fraud. The four risks covered in this report are not theoretical. They affect hundreds of thousands of transactions every year. The buyers most exposed are those who purchase privately, skip the history check because the car looks good and the seller seems credible, and only discover the problem when they try to sell the car on or when a bailiff knocks on the door.
The data also shows a clear shift in criminal targeting. Fraudsters and thieves are following money: the models that attract the most fraud are the ones with the highest mileage-linked residual values, the best parts demand, and the highest finance balances outstanding. As the UK fleet moves towards more expensive hybrid and electric vehicles, the incentive for these forms of fraud only increases.
Frequently asked questions
What are the biggest risks when buying a used car in the UK?
The four most significant hidden risks when buying a used car in the UK are outstanding finance, mileage fraud, insurance write-off history, and stolen vehicle status. Industry data shows that approximately one in four used cars checked carries outstanding finance, around 2.1% have had their mileage fraudulently altered, 4% have been written off by an insurer at some point, and a significant number are recorded as stolen on the Police National Computer. A comprehensive vehicle history check will reveal all four of these risks before you commit to a purchase.
How many used cars are sold with hidden problems in the UK each year?
The scale is substantial. An estimated 160,000 cars change hands each year with fraudulent mileage readings. Roughly 25% of the used cars that undergo a history check are found to have outstanding finance, meaning the finance company — not the seller — holds legal ownership. Around 60,900 cars were reported stolen in 2025 alone, some of which will enter the used market in a disguised form. And 4% of checked vehicles carry an insurance write-off category on their record. Taken together, these risks affect millions of transactions in the UK used car market every year.
Which models are the highest risk to buy used?
No model is risk-free, but certain cars consistently appear across multiple risk categories. The Nissan Qashqai is the UK's most clocked car, with nearly 10% of checked examples showing mileage fraud. The Ford Fiesta is the most stolen model by volume. The Land Rover Defender has the largest average mileage rollback on clocked examples and also appears in high-value theft statistics. Premium German models including the Audi A6, BMW 5 Series, and Mercedes-Benz E-Class feature in both mileage fraud and high-value theft rankings. Popular finance-heavy models like the Ford Focus and Nissan Qashqai also carry elevated outstanding finance risk simply due to the volume of PCP agreements against them.
Does a vehicle history check cover all four risks?
A comprehensive vehicle history check from Check Car Details covers all four major risk categories: outstanding finance, mileage history and discrepancies, insurance write-off status and category, and stolen vehicle status against the Police National Computer. It also includes keeper history, plate change records, import and export status, and ULEZ compliance information. Running a check before purchase is the single most effective step any used car buyer can take.
