Our Verdict
The 2015 Bentley Mulsanne presents a mixed proposition. While its MOT history shows mostly clean results, recent tyre and brake issues warrant caution. This example offers luxury but requires careful inspection of critical components.
Prioritise a thorough inspection of the front brake discs and rear tyres, as these were flagged in the 2025 MOT. Verify service history for any missed maintenance, particularly brake system servicing. Negotiate based on the tyre and brake repairs needed. Check for signs of luxury interior wear given the vehicle's age and mileage. Be wary of potential electrical system issues common in older Bentleys.
As a 6.8L petrol engine, this Mulsanne will have poor fuel economy (estimated 18-22 mpg). Road tax is £285 annually (2025 rates for 0-50g/km CO2). Insurance groups for large luxury cars typically range £100-£150+ annually. Maintenance costs will be high due to complex systems, with brake repairs and tyre replacements likely within 12-18 months. Annual running costs could reach £2,500-£3,500.
Focus on the front brake discs for warping or excessive wear, as noted in the 2025 MOT. Check both rear tyres for tread depth and structural integrity. Inspect the engine bay for fluid leaks and the suspension for unusual noises. Verify that all electrical systems (including climate control and infotainment) function correctly. Review service records for brake fluid changes and tyre rotations.
This 2015 Bentley Mulsanne has a generally clean MOT history with only minor issues recorded in its most recent test. At 41,110 miles, the mileage is above average for its age, though the vehicle has shown consistent maintenance. The black colour and 6.8L petrol engine align with typical Mulsanne specifications, but the lack of aggregate reliability data means risks remain unquantified.
No aggregate MOT data available for the Bentley Mulsanne model to assess general reliability trends.
