2011 Bentley Mulsanne 6.8L Petrol · KB56 KPB

The 2011 Bentley Mulsanne presents a completely clean MOT record. The most recent test, conducted on 29 May 2026 at 52,381 miles, passed with zero defects, advisories, or failures. This marks five consecutive years of first-time passes with no recorded faults whatsoever. The maintenance trend is stable and exceptionally strong, indicating consistent, thorough upkeep across multiple annual tests. The mileage pattern reinforces this picture of careful, low-intensity use. Between June 2022 at 48,613 miles and May 2026 at 52,381 miles, the car covered just 3,768 miles over nearly four years. That averages roughly 942 miles per annum across the most recent period, well below the already modest lifetime average of approximately 3,492 miles per year. There are no sudden jumps or suspicious gaps in the odometer record. The annual tests fall within a tight June-to-May window each year, suggesting a predictable servicing and testing routine rather than sporadic use. Despite the flawless MOT history, a buyer should still commission an independent inspection focused on areas the MOT does not fully stress-test. At fifteen years old, even low-mileage luxury vehicles can develop latent issues. The air suspension system, a known wear item on the Mulsanne, deserves close scrutiny for compressor health, air spring leaks, and ride-height calibration. The power steering rack and hydraulic components should be checked for fluid seepage, as age-related seal deterioration can occur regardless of mileage. Brake calipers, discs, and flexible hoses merit attention given the extended periods of low use, which can cause surface corrosion on brake components and deterioration of rubber hoses. Underbody and subframe corrosion should be inspected, particularly around suspension mounting points and jacking points. The 6.75-litre V8 engine and its twin turbochargers should be assessed for oil leaks, coolant condition, and the integrity of ancillary drive belts and tensioners. Interior electrics, including seat mechanisms, infotainment systems, and climate control, should be fully operational tested, as these complex systems can develop intermittent faults that an MOT does not capture.
