AI car check for a clearer vehicle history
Enter a UK registration for a free AI car check. RegAdvisor reads available MOT and vehicle records, highlights recurring findings and turns the history into practical questions for owners and buyers.
Recorded findings, then practical guidance
RegAdvisor highlights the latest MOT result, repeated observations and recorded mileage. Each finding links to its supporting test entry so you can check the evidence yourself.
Additional AI guidance suggests general next steps for an owner or a buyer. It cannot establish whether a car is currently safe, well maintained or a sensible purchase.
A tyre advisory appears on two test dates. Those entries do not establish whether repairs were made. Check the tyre’s current condition and any repair records.
What to look at
- Latest test defects and advisories, with the test date.
- Observations repeated across different test dates.
- Recorded mileage, its units and changes that need checking.
- What the records leave unknown, including the car’s condition today.
Plan the questions behind running costs
Costs depend on the exact variant, local labour rates, the vehicle’s condition and your circumstances. RegAdvisor gives general guidance on obtaining servicing, tyre and insurance quotes, rather than presenting unverified figures as personalised estimates.
Check the vehicle’s tyre size, request itemised repair quotes, and use your own details for insurance. Use current official guidance for vehicle tax.
How AI car history analysis actually works
RegAdvisor fetches official data from two UK government sources: DVLA (vehicle registration, tax status, colour, engine size, CO₂) and DVSA (available MOT records, including results, odometer readings and recorded defects).
Recorded findings are derived from the returned MOT entries. AI guidance is generated separately, checked for complete structured output, and labelled as guidance rather than official data.
If the additional guidance is unavailable, the recorded findings and MOT history stay usable. We do not treat a clean MOT history as a guarantee of current condition.
What AI can't tell you
AI analysis has real limits, and it's worth being honest about them:
- It cannot detect unrecorded accidents; a paid check may also have gaps in its coverage
- It can't confirm whether outstanding finance exists on the vehicle
- It can't replace a physical inspection by a trained mechanic
- Its reliability notes are based on general model knowledge, not live owner data
AI guidance on RegAdvisor is based on publicly available DVLA and DVSA data. It is intended to help you ask better questions — not replace a professional inspection or a paid history check for high-value purchases.
AI vs a standard car history check — what's the difference?
Paid car history services like HPI Check or AutoTrader's history check are worth using for any serious purchase. They cover things RegAdvisor doesn't: finance outstanding, insurance write-off categories, stolen vehicle status, and plate change history.
What AI adds is interpretation. A paid check will tell you whether a car has had three MOT failures. AI will tell you whether those failures suggest a pattern worth worrying about, or whether they're minor items consistent with normal wear on a high-mileage car.
The sensible approach for a used car purchase is to use both: free AI analysis to shortlist and understand the history, and a paid check before you hand over money.
