Inside the surviving fleet
AutoCensus parses every DVLA variant description, so the fleet can be read by fuel and specification rather than as one number.
First registrations by year
When surviving examples first joined the British fleet.
New registrations
Vehicles first registered each year. A fleet still being sold shows here; a finished one shows only imports.

Pass rate by year
| Failure reason | Failures | Share of all tests |
|---|---|---|
| The windscreen washers do not provide enough liquid to clear the windscreen in conjunction with the wiper(s) | 1,747 | 3.2% |
| A stop lamp inoperative or less than 50% of the light sources illuminating | 1,118 | 2.0% |
| The calculated parking brake efficiency is too low | 1,089 | 2.0% |
| The horn inoperative | 955 | 1.7% |
| A wiper blade insecure, missing or in such a condition that it does not clear the windscreen effectively to give the driver an adequate view of the road (through the windscreen) to the left and right sides of the vehicle, as well as to the front | 634 | 1.2% |
| A low braking effort is recorded from the parking brake on any wheel, indicating clearly that the brake is not functioning correctly | 596 | 1.1% |
| The calculated out-of-balance of the brakes across an axle is greater than 30% | 571 | 1.0% |
| Amalgamation of failures for all headlamp testers | 569 | 1.0% |
Counted across every recorded test, 2005 to 2025. Advisories are excluded.
Where the Tr6 remains
Based on MOT test locations, 2025. Test location is a proxy: a vehicle is counted where it was last tested, not where it is kept.

Full methodology
Population figures count vehicles recorded as licensed or SORN in the DVLA quarterly extract. Figures before 2014 cover Great Britain only. Vehicles are grouped into this family by the DVLA GenModel key shown above, with routing rules for known inconsistencies.
Variant figures are parsed from raw DVLA model descriptions and the original string is always retained. Blank transmission fields are shown as manual because DVLA records the field for automatic vehicles.
MOT figures count tests, not vehicles, and geographic figures count each vehicle at its most recent test location. The decline projection is a straight line fitted to the latest five years and is illustrative only.
