1996 Mercedes-Benz 609 D 4.0L Diesel · P59 RAB

The vehicle’s most recent MOT test on 2023-06-08 confirmed roadworthiness with no defects, though it was preceded by a curious failure on 2023-06-07 with no recorded issues—an anomaly that suggests either a temporary administrative error or a last-minute correction. The preceding test in 2022-05-24 also passed without faults, indicating a stable maintenance record over the past four years. However, the lack of any advisories or recurring faults in the MOT history does not preclude hidden wear; the absence of test failures on critical systems like suspension, brakes, or emissions implies routine upkeep was maintained, but the vehicle’s age (30 years) and mileage (222,398) necessitate a thorough inspection of high-wear components. The recorded mileage of 222,398 miles aligns with typical usage for a vehicle of this age, averaging around 7,400 miles annually—a rate that suggests consistent driving rather than prolonged neglect or excessive idling. The gap between the 2022 and 2023 tests spans 13 months, which is slightly longer than the standard 12-month MOT cycle but not unusual given the vehicle’s age. There are no red flags in mileage accumulation, though the abrupt failure followed by a pass in consecutive days warrants scrutiny of whether the vehicle was driven to the test centre in a minimal condition or if there was an oversight in documentation. Given the vehicle’s age and mileage, a buyer should prioritise an inspection of the suspension system, particularly the rear coil springs and bushes, which are prone to fatigue and corrosion in high-mileage Mercedes-Benz models. The braking system—especially rear calipers and discs—should be checked for uneven wear or binding, as the 2023 failure suggests potential issues that weren’t captured in the test. Structural integrity is another concern; the chassis and subframe should be examined for rust penetration, particularly around wheel arches and sills, while the exhaust system should be inspected for leaks or excessive corrosion, given the vehicle’s age. Tyre tread depth and condition, though not flagged in MOTs, will have deteriorated significantly over time, and wiper blades should be replaced as they are consumables with a limited lifespan.
