2017 Bentley Mulsanne 6.8L Petrol · 40 MA

The most recent MOT inspection on 29 January 2026 resulted in a pass, although it carried an advisory regarding the condition of the front tyres. Reviewing the overall MOT history, the maintenance trend appears stable and consistent. Aside from a single major failure in January 2025 concerning damaged offside rear seat belt webbing, the vehicle has consistently met the required safety standards. This history suggests a vehicle that is generally well-maintained, though the recent advisory indicates that age-related degradation is now becoming a factor in its roadworthiness. The recorded mileage of 31,016 miles over a nine-year period represents an exceptionally low annual average of approximately 3,446 miles. While this suggests minimal wear on the engine, transmission, and drivetrain components, such low usage can be a double-edged sword. Vehicles that spend long periods stationary are susceptible to different mechanical issues than high-mileage cars, particularly regarding the integrity of rubber seals, the degradation of fluids, and the health of the electrical systems. The low mileage profile suggests this Bentley has likely been used for occasional leisure rather than regular commuting, which necessitates a specific inspection approach. The advisory regarding cracking and perishing on the outer edges of the front tyres is a classic symptom of rubber age and low usage. During your test drive, listen for any rhythmic thumping or increased road noise, which could indicate tyre deformation or flat-spotting from standing. You should also inspect the tyre sidewalls closely for any deep cracks or bulges. Given the vehicle's age, it is vital to verify that the tyres are relatively recent; even with ample tread, older rubber loses its grip and structural integrity. I would also recommend checking the brake discs for heavy corrosion or pitting, as infrequent use can allow surface rust to build up, potentially leading to binding calipers or uneven braking performance. In addition to the tyres and brakes, you must scrutinise the vehicle for signs of time-based degradation. Inspect all suspension bushes and engine mounts for cracking or perishing, as these components can fail due to age even if they have not been subjected to high mileage. Check the service history specifically for evidence of interval-based maintenance, such as annual oil changes or fluid flushes for the coolant and brake systems, which are essential for preventing internal corrosion and seal failure. Finally, pay close attention to the electronic systems during startup and operation, as low-use luxury vehicles are highly sensitive to battery health and can suffer from voltage-related faults if the 12V battery has not been regularly maintained or charged.
