Why This Matters
Buying a used car can be a minefield. Hidden problems like mileage rollbacks, write-offs, recurring MOT failures, or import status can cost you thousands down the line. That’s why we used AI to scan over 1 million MOT records, history checks, and DVLA entries to find the 20 models that pose the highest risk in 2025.
How We Did It
Car Owl’s AI engine crunched data from:
- MOT advisory and failure rates
- Recorded write-off and insurance claims
- Number plate changes (often used to hide history)
- Imported vehicle patterns and mileage discrepancies
- Market value vs. typical repair costs
This allowed us to identify cars with statistically higher odds of being problematic when bought used.

Frequently Asked Questions About Risky Used Cars
What makes a used car risky to buy?
A risky used car typically has hidden issues like a history of write-offs, clocked mileage, high MOT failure rates, or being a hidden import. These issues can lead to expensive repairs or even make the vehicle unsafe.
How was this list of risky cars created?
We used Car Owl’s AI to analyse over 1 million UK vehicle records, including MOT history, write-off data, plate changes, and import status. The models with the highest risk factors made our top 20 list.
Is it safe to buy a car from this list?
Yes — but only if you do your due diligence. Many cars on the list are safe when well-maintained. We recommend running a full vehicle history check to uncover any hidden issues before buying.
Can I check if my car is on the risky list?
Yes, simply type your registration into our checker and you’ll see a summary of potential risks for your vehicle, including write-off history, mileage concerns, and known faults.
What does a high MOT failure rate mean?
It means that a large percentage of that vehicle model fails its MOT, often due to recurring mechanical or structural issues. This can be a sign of higher ownership costs or reliability problems.
How can I protect myself from buying a bad used car?
Use Car Owl’s history check before buying. Look out for plate changes, import status, advisory-heavy MOT records, and suspiciously low mileage. Ask the seller for full service history and be prepared to walk away.
Why are import cars riskier?
Imported vehicles — especially grey imports — may not meet UK specs, might have mileage discrepancies, and can lack consistent maintenance history. They're often harder to insure or repair.
Do risky cars cost more to insure?
In many cases, yes. Cars with poor MOT history, high claim rates, or limited parts availability may lead to higher insurance premiums or excess fees.
Can I trust Car Owl’s data?
Yes. Our checks use verified sources such as the DVSA, DVLA, insurance records, and AI modelling across millions of real UK vehicle records. We aim to give buyers the full picture.
Is this tool free to use?
Our basic reg check is free, and we offer affordable full vehicle history reports for deeper insights. You’ll see key warnings before committing to any purchase.
