Our Verdict
A highly attractive, low-mileage example of the Mulsanne, though it shows signs of 'sitting' rather than being driven. Recommended for a buyer who prioritises exclusivity and low usage, provided a full mechanical refresh is conducted.
The primary concern with this vehicle is its inactivity. The 2025 MOT records multiple tyres as 'damaged, cracking or perishing', which is a classic sign of a car that has sat for long periods. Ensure that all four tyres have been replaced recently, as perished rubber is a safety risk regardless of tread depth.
Carefully review the service history to ensure the oil has been changed annually, regardless of the low mileage. Pay close attention to the power steering system; the 2020 failure and 2021 'slight seepage' indicate a recurring weak point that should be professionally inspected for current leaks before purchase.
Owning a 6.75-litre V8 Bentley is a significant financial commitment. Fuel economy will be very low, particularly in urban environments, and the high engine displacement places it in the highest possible tax bracket.
Insurance for a Mulsanne is substantial due to the vehicle's value and repair costs. Maintenance will be expensive, as parts and specialist labour for the Mulsanne carry a premium. Expect annual running costs to be high, primarily driven by fuel and specialised servicing requirements.
Focus your inspection on the tyres and braking system. The January 2025 MOT noted that both front brake discs were worn, and three tyres were perishing; verify that these have been replaced with high-quality equivalents.
Inspect the power steering rack and associated hoses for any signs of fluid leakage, referencing the failures recorded in December 2020 and January 2021. Finally, check the windscreen washer system to ensure the fault that caused the 2025 failure was fully rectified and not just a temporary fix.
This 2012 Black Bentley Mulsanne has covered remarkably low mileage, totaling just 33,627 miles over 14 years. While the odometer is impressive, the MOT history suggests a vehicle that has spent significant time stationary, evidenced by tyre perishing and a previous power steering leak. It remains a prestigious purchase, but the low usage introduces specific maintenance risks.
Aggregate data is unavailable for this specific model, but the Mulsanne is generally regarded as a hand-built luxury flagship where maintenance history is more critical than general reliability statistics.

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.
