Diamante
Mitsubishi · on record 2002 to 2016
The Mitsubishi Diamante is the Japanese and export name for a large Mitsubishi executive saloon closely related to the Sigma sold in Britain. Buyers placed the Diamante toward the more expensive end of the range, where cabin quality, refinement and status mattered as much as basic transport. Older Diamante examples increasingly depend on values, specialist servicing and owner commitment, because complex luxury cars are preserved on very different terms from ordinary family transport.

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 |
|---|---|---|
| A mandatory rear fog lamp missing, insecure, obviously incorrectly positioned or does not face to the rear | 7 | 9.2% |
| A low braking effort is recorded from the parking brake on any wheel, indicating clearly that the brake is not functioning correctly | 5 | 6.6% |
| 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 | 4 | 5.3% |
| A direction indicator missing, insecure, obviously incorrectly positioned or does not face to the front, rear or side as appropriate | 4 | 5.3% |
| The grooves of the tread pattern are not at least 1.6mm throughout a continuous band comprising the central three-quarters of the breadth of tread, and round the entire outer circumference of the tyre | 4 | 5.3% |
| A stop lamp inoperative or less than 50% of the light sources illuminating | 4 | 5.3% |
| An obligatory lamp shows a light other than red to the rear and white to the front (or yellow if a front position lamp is incorporated in a yellow headlamp) | 4 | 5.3% |
| A major leak of exhaust gases from any part of the system | 4 | 5.3% |

Where the Diamante remains
Based on MOT test locations, 2017. 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.
