Illustrative car for inspection areas

Each MOT test can include an odometer reading as testers record it. Over years of ownership those readings form a trace you can compare to an advert or the dashboard — provided DVSA published mileage for those tests. Car Buyer Check plots the sequence on the buyer report timeline and surfaces gaps when readings are missing or unusable.

What the mileage trace can show

In normal use you expect readings to rise between tests as the car is driven. The timeline lists test dates with the mileage written on that day, so you can see long gaps between tests, periods of heavy use, or stretches with no mileage returned in the feed. The free preview includes the latest recorded mileage in the MOT snapshot when it is available, plus pass/fail context.

When no usable mileage comes back despite tests being present, the report can flag mileage unavailable. That is a gap in the record, not a statement about whether the odometer is honest. Compare the advert, V5C, and any service history yourself.

Mixed units and anomalies

Occasionally readings switch between miles and kilometres on different tests. The engine treats mixed units as a separate finding: it does not chain those numbers into a single trend because the comparison would be misleading. That flag is a prompt to ask questions, not an accusation.

If a later test shows a lower number than an earlier one in the same units, that is handled as a mileage-decrease pattern on its own guide. This page is about reading the overall trace and missing data, not interpreting a single drop.

Using a registration check

Enter the plate in the hero form. The government snapshot may show the latest mileage from MOT History when connected. The free preview adds buyer position and marked areas from defect patterns; the buyer report opens the full dated timeline with each reading alongside MOT results and interpreted findings.

  • Use seller questions from the report when mileage gaps or mixed units appear.
  • Cross-check the odometer at the viewing against the most recent MOT reading and the advert.
  • Remember MOT mileage is what was recorded on test day — not live telematics.

Car Buyer Check does not verify clocking, finance, or identity beyond the government fields we display. Mileage work is about facts on the file and sensible questions for the seller.

Official sources

Is MOT mileage always recorded?

Not always. Some tests in the feed lack a usable reading. We flag that as unavailable mileage rather than guessing a number.

Can I see every mileage reading in the free preview?

The preview highlights the latest reading in the snapshot and summary stats. The full chronological list is in the buyer report timeline.

Why might advert mileage not match MOT History?

The car may have been driven since the last test, the advert may be rounded, or the listing may contain a typo. Use the trace to structure your questions — we do not label that mismatch as fraud.

Does a steady rise between MOTs prove the odometer is genuine?

A rising trace is what you usually expect, but it is not a guarantee. It only reflects what testers recorded on those dates.

Where does the mileage data come from?

From DVSA MOT History for Great Britain, combined with DVLA identity fields when connected for the same registration lookup.
