Our Verdict
This 2013 Bentley Mulsanne (BU57ALO) is a strong used purchase for those seeking a low-mileage luxury saloon with a clean recent MOT record. The only minor advisory in the last five years was slight power steering seepage, which has not recurred in the latest test.
Given the clean MOT record, focus your negotiation on service history, which is not included in the supplied data and is critical for a 6,752cc Bentley. Confirm the timing chain, suspension, and brake servicing have been completed to schedule by a marque specialist, as costs for skipped work are substantial. The 2024 advisory for slight power steering seepage should be verified as resolved; ask for proof of inspection or renewal of the rack seals at the 2026 MOT.
As a 6.75-litre petrol engine, expect poor fuel economy, likely in the low-to-mid teens of mpg in mixed use, with road tax in the highest band for pre-April 2017 vehicles. Insurance group will be among the highest available given the value and performance of the Mulsanne. Annual maintenance at a Bentley specialist should be budgeted separately from fuel and tax, with major services costing several thousand pounds.
Physically inspect the front power steering rack area for any fresh seepage, referencing the 2024 MOT advisory at 32,330 miles that noted slight seepage from a component; the 2026 test at 33,302 miles recorded no defects, suggesting it was monitored or addressed. Check the grey paintwork and interior for condition consistent with the low 33,302-mile use, and verify tyres and brakes match the age and weight of the car. As no aggregate model data is available, rely on the individual MOT history showing no failures and only one minor advisory across five tests.
The vehicle shows a consistent and low mileage history, rising from 27,787 miles in August 2021 to 33,302 miles by May 2026, averaging under 1,500 miles per year. MOT records between 2021 and 2026 show four passes with no defects and one pass with a minor power steering rack seepage advisory that was not repeated at the 2026 test. As a November 2013 registered grey 6.75-litre petrol Mulsanne, it represents a well-kept example of a rare flagship saloon. No MOT failures are present in the supplied history.
No aggregate MOT reliability data is available for the Bentley Mulsanne, so assessment is limited to this vehicle's individual history showing no failures.

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.
