1986 Bentley Eight 6.8L Petrol · C541 BNX

The most recent MOT test on 19 May 2023 at 149,620 miles confirmed the vehicle as roadworthy with no defects recorded. This represents a stable maintenance trend over the past three years, as the preceding test on 11 June 2022 at the same mileage also passed without fail. The absence of advisories or recurring faults suggests the vehicle has not undergone significant mechanical or structural interventions between these dates, though the 2023 test occurred just over three years ago—nearly a full MOT cycle past its due date. Given the vehicle’s age and the extended gap since the last inspection, a thorough professional check is essential to verify the integrity of high-wear components. The recorded mileage of 149,620 miles over approximately 40 years equates to an average of around 3,740 miles annually, which is unusually low for a vehicle of this vintage. The lack of mileage progression between the 2022 and 2023 tests—both at 149,620 miles—indicates prolonged periods of inactivity, which could exacerbate issues such as suspension perishing, brake fluid degradation, or fuel system contamination. Such stagnation also raises questions about storage conditions, as prolonged standing increases the risk of corrosion, particularly in critical areas like the subframe, wheel arches, and exhaust system. Given the sparse MOT history, a buyer should prioritise an inspection of the suspension system, including coil springs, bushes, and shock absorbers, for signs of dry rot or excessive wear. The brakes—particularly the rear calipers and discs—should be checked for binding or uneven wear, as binding calipers were a common failing in pre-1990 high-performance vehicles. Structural integrity is another critical concern; a thorough examination of the chassis, sills, and wheel arches for corrosion or distortion is mandatory, especially given the vehicle’s age and the implied periods of disuse. Additionally, the fuel system, including injectors and fuel lines, warrants attention due to the risk of sediment buildup from prolonged storage.
