Our Verdict
This 2015 Bentley Mulsanne is a low-mileage luxury saloon with a broadly clean MOT record, but buyers should budget for specialist upkeep and verify the registration plate issue was properly resolved. It remains a desirable flagship model, though running costs will be considerable given the 6.75-litre petrol engine.
Given the Mulsanne's low annual usage (under 1,000 miles per year on average), confirm the service history is up to date with Bentley main dealer or recognised specialist stamps, as infrequent use can mask overdue maintenance. The 2020 MOT failure for honeycomb-effect registration plates must be checked as resolved with standard plates fitted, since this was a simple but notable compliance failure. Negotiate on the basis that the 2021 advisory for offside rear shock absorber misting and the 2019 nail-in-tyre-with-sidewall-cut indicate minor wear items that may need attention.
As a 6,752cc petrol engine luxury car, the Mulsanne will fall into the highest VED tax band and return poor fuel economy, likely under 20 mpg in real-world use. Insurance groups for such vehicles are at the top end, and specialist maintenance or parts will be expensive compared to mainstream cars. Estimated annual running cost including fuel, tax, insurance and typical maintenance is likely to be several thousand pounds given the engine size and marque.
Inspect the front and rear registration plates to confirm they meet UK standards following the 2020 failure for honeycomb background effect, as non-compliant plates can cause MOT issues. Check the offside rear shock absorber for oil misting noted in the 2021 MOT, and look for any deterioration in suspension ride quality given the car's weight. Review the tyres carefully, especially the nearside rear which had a nail and sidewall cut in 2019, and ensure all tyres are correctly aged and undamaged given the low but ageing mileage.
The vehicle shows remarkably low mileage for its age, with just 7,981 miles recorded at its 2022 MOT against a 2015 first registration. MOT history is mostly clean, with only a 2020 failure for non-conforming honeycomb-effect registration plates and minor advisories for shock misting and a tyre defect. No aggregate model reliability data is available, so condition assessment relies solely on the individual history provided.
No aggregate MOT reliability data is available for the Bentley Mulsanne, so this assessment is based solely on the individual vehicle's history.

AI Analysis
Historical fault & advisory patterns
Common Problems: BENTLEY MULSANNE
Known issues reported by owners and MOT testers.
- Power Steering Pump Failure(Serious)
The hydraulic steering pump can fail, leading to heavy steering or noisy operation.
- Coolant Expansion Tank Leaks(Moderate)
The plastic expansion tanks can crack or the seals can fail, leading to slow coolant loss.
- 6.75L V8 Turbo Oil Feed Line Leaks(Serious)
The legendary 6.75-litre V8 uses turbo oil feed lines that can develop leaks as they age, leading to oil consumption, potential turbo damage, and in severe cases engine bay fires if oil contacts hot exhaust components.
MOT Status
No MOT history available
No MOT test records were found for this registration. DVSA’s digital archive only covers tests from 2005, so a vehicle that has not been tested since then may legitimately have no visible history.
