2020 Mercedes-Benz S 350 L Grand ED Executive D A 2.9L Diesel · EA20 BTO

The vehicle’s most recent MOT test on 2025-06-13 at 62,466 miles confirms it remains roadworthy without any recorded defects, maintaining a consistent pass history across the last three annual tests. This suggests no recurring mechanical failures or safety-critical issues have been overlooked, though the absence of advisories or defects in the record does not preclude hidden wear—particularly in high-mileage luxury vehicles where consumable components like suspension bushes, coil springs, or brake calipers may degrade incrementally. The tester’s clean bill across 2023, 2024, and 2025 implies either disciplined servicing or that the vehicle’s critical systems have thus far resisted premature failure, though the lack of advisory notes means no prior warnings about specific wear patterns have been documented. The mileage progression reveals a steady accumulation of approximately 10,411 miles annually, which aligns with typical usage for a vehicle of this age and class. There are no abrupt jumps or prolonged periods of inactivity between tests—from 36,223 miles in June 2023 to 45,376 in June 2024, and then to 62,466 in June 2025, the increments are consistent and reasonable. This pattern suggests the vehicle has been driven regularly rather than stored, reducing the risk of neglected fluid degradation or seized components. However, the absence of service records beyond MOTs means critical intervals for oil changes, timing belt inspections, or differential fluid refreshes cannot be verified. A buyer should prioritise an independent inspection of the suspension geometry, particularly the rear subframe and bushings, given the vehicle’s age and mileage. The lack of advisory notes does not rule out subtle deterioration in coil springs or sway bar links, which often fail silently before causing handling issues. Brake systems warrant scrutiny—while no binding calipers or excessive disc wear were logged, luxury vehicles of this type are prone to high-performance brake fade or rotor glaze over time. Additionally, the exhaust system should be checked for corrosion or leaks, as emissions systems in Mercedes-Benz models can develop subtle faults that aren’t always caught in a basic MOT. Finally, the underbody and wheel arches should be examined for signs of structural corrosion, especially around the sills and rear subframe, as this is a common failure point in vehicles of this age when exposed to UK road conditions.
