Population history
Licensed and SORN vehicles at each census. Filters apply to the population, MOT and registration figures together.

SORN
Latest census observation
At the average decline recorded over the latest five years, the licensed fleet would reach zero around 2056.
Illustrative projection only; vehicle populations rarely decline linearly. Late fleets typically flatten as surviving examples enter preservation.
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.
Recent UK first registrations
This family is no longer sold new. These figures are imports and historic vehicles joining the British register for the first time.

DVSA test results for this family, 2005 to 2025.
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) | 56 | 3.8% |
| The calculated out-of-balance of the brakes across an axle is greater than 30% | 53 | 3.6% |
| The calculated parking brake efficiency is too low | 40 | 2.7% |
| Deliberate modification which significantly reduces the original strength, excessive corrosion, severe distortion, a fracture or an inadequate repair of a load bearing member or its supporting structure or supporting panelling within 30cm of any sub- | 31 | 2.1% |
| Any deliberate modification, excessive corrosion, damage, cracks or inadequate repair of a load bearing body or chassis member which seriously affects its strength within 30cm of the body mountings | 26 | 1.8% |
| A major leak of exhaust gases from any part of the system | 23 | 1.6% |
| 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 | 22 | 1.5% |
| A stop lamp inoperative or less than 50% of the light sources illuminating | 20 | 1.4% |

Where the A55 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.
