What does the VEHIXA AI risk score mean?

VEHIXA's AI risk score is a three-tier verdict — Low, Moderate, or High — that summarises the overall risk profile of a used car. It is derived by analysing eight risk dimensions simultaneously: finance status, write-off history, mileage consistency, MOT advisory patterns, keeper velocity, valuation anomalies, vehicle identity consistency, and stolen status. The score is accompanied by the specific factors that drove each tier and recommended actions for the buyer.

Does a "Moderate" risk score mean I should not buy the car?

A Moderate score means the AI identified one or more risk factors that warrant investigation before buying — not that you should automatically walk away. A Moderate score might reflect a write-off marker that may be entirely benign (a minor Cat N with a clean MOT record since repair) or a mileage anomaly that has an innocent explanation. The score is a signal to investigate further, not a definitive veto. The specific factors listed with the Moderate verdict tell you what to investigate.

What causes a High risk score?

A High risk score typically reflects one or more of: outstanding finance (the car is legally owned by a lender and can be repossessed), a stolen marker, an unresolved write-off (especially Cat A or B where repair may be prohibited), a significant mileage discrepancy suggesting clocking, or a combination of multiple Moderate-level risk factors that together indicate elevated concern. High risk does not necessarily mean the car is undriveable — but it means significant risks were identified that must be resolved before purchase.

Is the VEHIXA AI risk score the same as an insurance write-off category?

No. Insurance write-off categories (A, B, S, N) are part of the data VEHIXA reads from Experian, not the risk score itself. The risk score is VEHIXA's AI assessment of the full vehicle profile, which includes write-off status as one of eight input factors. A Cat N write-off does not automatically produce a High risk score if all other factors are clean — it will produce a Moderate score with the write-off as the flagged factor.

Why a Single Score Matters

A full vehicle history check returns dozens of data points: MOT dates, mileage at each test, advisory text, failure reasons, finance status, write-off category, keeper count, plate changes, and more. For someone who runs vehicle checks professionally, each data point is meaningful. For a private buyer deciding whether to buy a car, an uninterpreted list of records is not actionable.

The risk score synthesises all of those data points into a single verdict that answers the practical question: "Based on everything the data shows, how risky is this car?" The score is accompanied by the specific factors driving it — so buyers who want to understand the detail can, while those who need a quick answer get one.

The Eight Risk Dimensions

VEHIXA's AI evaluates eight dimensions of risk simultaneously, drawing from all three data sources:

Finance Status

Experian

Is the vehicle subject to outstanding finance? Finance secured on a vehicle runs with the car, not the seller. A car with outstanding finance can be legally repossessed by the lender even if the buyer purchased in good faith and paid in full.

Outstanding finance → automatic High risk flag

Write-Off History

Experian

Has the vehicle been written off by an insurance company? Categories A and B are the most severe (prohibited from road use / parts only). Cat S (structural damage) and Cat N (non-structural damage) are repaired and returned to road, but carry reduced values and require disclosure.

Cat A/B → automatic High. Cat S/N → Moderate with context evaluation.

Stolen Status

Experian / Police

Is the vehicle registered as stolen on the Police National Computer? Buying a stolen vehicle means the car can be seized at any time, and the buyer loses both the car and the money paid.

Stolen marker → automatic High risk flag

Mileage Consistency

DVSA

The AI plots mileage at every recorded MOT test and calculates whether the progression is physically consistent. Odometer reductions (clocking), implausible plateaus, and suspicious step changes are flagged with severity ratings.

Any confirmed reduction → High. Anomalies → Moderate pending investigation.

MOT Advisory Patterns

DVSA

What does the advisory record reveal about maintenance quality? Recurring advisories for the same component, increasing failure frequency, and clusters of unresolved advisories all indicate deferred maintenance that translates to costs for the buyer.

Isolated resolved advisories → Low. Recurring unresolved → Moderate. Escalating failures → High.

Keeper Velocity

Experian / DVLA

How quickly have previous owners sold? Abnormally rapid keeper changes — especially those that correlate temporally with write-off dates, MOT failure clusters, or mileage anomalies — indicate buyers discovering problems and selling on.

Normal velocity → Low. Elevated velocity without event correlation → Moderate. Velocity correlated with negative events → High.

Valuation Anomaly

Market data

Is the car priced significantly below market value for its age and mileage? The trade prices cars with known issues (battery degradation, write-off history, persistent faults) below clean equivalents. An unexplained discount is often a signal the seller knows something the buyer does not.

In-range or slight discount → Low. Significant unexplained discount → Moderate flag.

Vehicle Identity Consistency

DVLA / Experian

Do the registration details, VIN, plate change history, and keeper records form a consistent identity? Plate retention, cherished transfers, and number plate changes are legitimate — but they require confirmation that the underlying identity is clean.

Plate changes with clean underlying history → Low. Anomalies → flagged for verification.

How the Tiers Work

Low Risk

No major flags across all eight dimensions. Finance clear. No write-off. No stolen marker. Mileage consistent. MOT advisories within normal range and resolved. Keeper velocity normal. Valuation in line with market. Identity consistent.

Buyer action: The history is clean. Arrange a viewing and commission a physical inspection as normal due diligence before purchase.

Moderate Risk

One or more risk factors identified that warrant investigation. Typically: a write-off marker (Cat S or N), recurring advisories, slightly elevated keeper velocity, a mileage anomaly without confirmed manipulation, or an unexplained valuation discount.

Buyer action: Do not walk away automatically. Investigate the specific flagged factors. Ask the seller for documentation. Commission a specialist inspection for the flagged component or history item.

High Risk

One or more critical flags identified: outstanding finance, stolen marker, Cat A/B write-off, confirmed mileage clocking, or multiple converging Moderate factors indicating a pattern. High risk does not mean the car is necessarily dangerous to drive — but significant issues must be resolved before purchase.

Buyer action: Do not proceed without resolution of the specific High-risk flags. Outstanding finance must be cleared by the seller and evidenced before you transfer money. Stolen vehicles should not be purchased under any circumstances.

What the Score Does Not Cover

The AI risk score is based entirely on official UK database records. It does not assess things that are not officially recorded:

Mechanical condition (not assessable without physical inspection)
Unrecorded accidents (accidents not reported to insurance)
Private repairs not appearing in any official record
Cosmetic condition
EV battery state of health

A Low risk score on a VEHIXA check means the recorded history is clean — not that the car is in perfect mechanical condition. A physical inspection is always recommended before purchase, regardless of the risk score.
