Allegro
Austin · on record 1994 to 2025
The Austin Allegro was a front wheel drive family car introduced by British Leyland as the successor to the highly successful 1100 and 1300. Available as saloon and estate, it used Hydragas suspension and a range of A Series and E Series engines. It became a familiar part of 1970s British motoring, and surviving cars now attract enthusiasts precisely because most ordinary examples were used, depreciated and disappeared.

Population history
Licensed and SORN vehicles at each census. The filters below apply to the family population, MOT and registration figures. They do not alter the generation history above.
Licensed
SORN
Latest census observation
At the average decline recorded over the latest five years, the licensed fleet would reach zero around 2181.
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.

Pass rate by year
| Failure reason | Failures | Share of all tests |
|---|---|---|
| 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- | 34 | 11.4% |
| The windscreen washers do not provide enough liquid to clear the windscreen in conjunction with the wiper(s) | 14 | 4.7% |
| The exhaust gas contains a carbon monoxide content exceeding the limit for a continuous period of 5 seconds | 10 | 3.4% |
| Significant braking effort recorded on a road wheel, even though the brake is not applied, indicating that a brake is binding | 9 | 3.0% |
| An insecure, split or missing steering rack gaiter | 9 | 3.0% |
| 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- | 8 | 2.7% |
| 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 | 8 | 2.7% |
| A stop lamp inoperative or less than 50% of the light sources illuminating | 7 | 2.4% |
Counted across every recorded test, 2005 to 2025. Advisories are excluded.
Where the Allegro 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 history combines DVLA VEH0120 Q4 census observations through 2013 with the annual VEH0220 census from 2014 onward. Figures before 2014 cover Great Britain only. Historical VEH0120 is used only when its overlapping UK observations reconcile to the current canonical family definition. Vehicles are grouped into this family using the DVLA GenModel together with durable routing rules for known inconsistencies.
Variant figures are parsed from raw DVLA model descriptions and the original string is always retained. Configuration is only assigned where the model description explicitly identifies it; a blank configuration is not treated as a two door Wrangler. 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.
