1991 Mercedes-Benz 420 4.2L Petrol · J871 ARR

The vehicle’s most recent MOT on 2023-11-02 at 155,080 miles showed no defects, indicating a stable maintenance trend over the past three years. Previous tests from 2021 and 2020 also passed without issues, though a 2020-06-04 failure at 150,675 miles recorded no defects, suggesting a possible administrative error or non-critical non-compliance. The absence of recurring mechanical faults in the record implies consistent upkeep, but the 36-month gap between the 2023 test and the current date raises concerns about potential undetected deterioration. The vehicle’s mileage of 155,080 miles over 35 years equates to approximately 4,431 miles annually, significantly below average for its age. This low usage could indicate infrequent operation or prolonged storage, increasing risks of corrosion, rubber component degradation, and fluid stagnation. Notably, the 2020-06-09 test at 150,698 miles and the 2018-02-08 test at 150,652 miles show minimal mileage progression, hinting at possible periods of inactivity. While the MOT history lacks defects, the sparse testing frequency and age necessitate closer scrutiny of wear-prone systems. A buyer should prioritise inspecting the vehicle’s structural integrity for rust, particularly in seams and underbody panels, given its age and low mileage. Suspension components, including bushes and coil springs, may exhibit wear from extended inactivity. The exhaust system and brake discs should be checked for corrosion, while the steering and suspension linkages should be assessed for play or binding. Despite the MOT record’s cleanliness, the vehicle’s vintage and usage pattern demand a thorough pre-purchase examination to confirm its mechanical soundness.
