Our Verdict
The 2012 Bentley Mulsanne presents a mixed proposition. While its recent MOT passed with no defects, a critical power steering failure in 2026 raises concerns about maintenance costs and long-term reliability. Careful inspection is advised before purchase.
Prioritise a thorough mechanical inspection focusing on the power steering system, which had a documented failure. Verify that the repair was fully completed and check for any recurring issues. Review service records to confirm regular maintenance, particularly for high-mileage components like the engine and transmission. Be prepared to negotiate on price given the recent MOT failure and the car's age. Consider having a specialist Bentley mechanic conduct a pre-purchase inspection to identify hidden issues.
As a 6.75-litre petrol flagship, the Mulsanne's fuel economy is poor, likely averaging 15-18 mpg. Road tax will be high due to its CO2 emissions, with an annual cost of £460+ for 2026. Insurance groups for luxury vehicles like this typically start at 50+, leading to premium costs well above average. Maintenance expenses will be substantial, with specialist repairs and parts likely to exceed £1,000 per major service. Estimated annual running costs: £2,000-£3,000.
Focus on the power steering system for leaks or unusual noises, as this was a documented failure point. Check the engine for oil leaks or unusual wear, given the high mileage. Inspect the transmission for smooth gear changes and check brake systems for excessive wear. Verify the condition of the leather upholstery and electrical systems, which can degrade in older luxury vehicles. Confirm that all MOT certificates match the recorded mileage and that the 2026 repair was properly addressed.
This 2012 Bentley Mulsanne has a mostly clean MOT history, with the most recent test passing at 38,727 miles. However, a significant power steering leak recorded in 2026 (38,724 miles) indicates potential mechanical vulnerabilities. The vehicle's high mileage for its age and lack of model-wide reliability data add to the caution required.
No aggregate MOT data available for the Bentley Mulsanne model, making it difficult to assess broader reliability trends. Individual vehicle history must be evaluated carefully.
