Our Verdict
This is a well-maintained 2012 Bentley Mulsanne with a reassuring MOT record, making it a confident used purchase for those who can afford the running costs. The absence of any MOT failures or recorded defects across the last five tests is a strong indicator of careful ownership.
Given the spotless MOT record, your main focus should be verifying the service history with a Bentley main dealer or specialist, as these 6.75-litre V8 models require documented scheduled maintenance to retain value. Negotiate on the basis of the low mileage and clean MOT, but budget for the reality that even routine work on a Mulsanne carries a significant premium over mainstream cars. It is worth confirming the grey paintwork and interior condition match the careful mechanical history suggested by the tests.
As a 6752cc petrol vehicle, the Mulsanne sits in the highest VED band and will return poor fuel economy, likely well under 20 mpg in real-world use. Insurance will be costly given the value, performance, and specialist repair needs, and maintenance at a Bentley specialist is expensive even without major faults. Estimated annual running costs including fuel, tax, insurance, and servicing are likely to exceed typical family cars by a wide margin.
The MOT history shows no failures and no defects across the 2021 to 2025 tests, so there are no specific failure types from the record to investigate. However, on a 2012 Mulsanne you should still inspect the air suspension for leaks or warning lights, check the large 6.75-litre V8 for any oil weeping, and verify the condition of the brake discs given the car's weight. A professional pre-purchase inspection by a Bentley specialist is strongly advised despite the clean MOT data.
The MX12LBL Mulsanne has covered just 60,517 miles since its June 2012 first registration, an exceptionally low figure for a 14-year-old luxury saloon. Its MOT history from 2021 to 2025 shows five consecutive passes with no defects recorded at each test. Without model aggregate data, we cannot benchmark reliability statistically, but the individual history here is clean and consistent.
No aggregate MOT data is available for the Bentley Mulsanne, so reliability cannot be benchmarked against other examples of the model.

AI Analysis
Historical fault & advisory patterns
Common Problems: BENTLEY MULSANNE
Known issues reported by owners and MOT testers.
- 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.
