Senator
Vauxhall · on record 1994 to 2025
The Vauxhall Senator was Vauxhall's large executive saloon of the 1980s and early 1990s, closely related to the Carlton but fitted with larger 6 cylinder engines and more luxury equipment. It appealed to buyers who wanted the particular mix of space, image and engineering represented by the Senator rather than a generic transport choice. Older Senator examples increasingly depend on values, specialist servicing and owner commitment, because complex luxury cars are preserved on very different terms from ordinary family transport.

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.

SORN
Latest census observation
At the average decline recorded over the latest five years, the licensed fleet would reach zero around 2031.
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.
New registrations
Vehicles first registered each year. A fleet still being sold shows here; a finished one shows only imports.

Where the Senator 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.
