2016 Mercedes-Benz E 3.0L Diesel · DE51 ADD

The Mercedes-Benz E in question presents a clean MOT history over the past year, with the most recent test on 9 October 2025 at 85,566 miles passing without any defects. This follows a pattern of consistent compliance since the previous two tests in October 2024 , where the vehicle also passed despite a rare administrative duplicate entry for a fail (likely a clerical error given the identical mileage). The absence of advisories or defects in the last three tests suggests the vehicle has been well-maintained in critical areas—braking, suspension, emissions, and structural integrity—at least up to the current mileage. That said, the two identical fail entries in October 2024 (78,568 and 78,570 miles) are unusual and warrant clarification from the seller, as they imply either a procedural oversight or an unresolved issue that was later rectified without retesting. The mileage accumulation of 85,566 miles over roughly 10 years aligns with typical usage for its age, averaging around 8,557 miles per year , which is neither excessively high nor low. The gaps between tests are standard—annual MOTs with no major mileage spikes—though the lack of advisories or defects in earlier records (2023 tests at 65,075 miles ) reinforces the impression of consistent upkeep. There’s no evidence of neglect or rapid degradation, but the absence of any recorded advisories also means there’s no historical baseline for wear items like brake pads, suspension bushes, or tyre condition beyond the last pass. For a buyer, the primary focus should be on consumable components that aren’t covered by MOT tests but degrade over time. Given the clean history, inspect the brake system —particularly the rear calipers and discs—for binding or uneven wear, as Mercedes E-Class models can develop stiffness in braking components even without MOT flags. Check the suspension for worn bushes, leaking dampers, or sagging coil springs, especially if the car has been driven on rough roads. Tyre condition is critical; while the MOT passed, verify tread depth and sidewall integrity, as uneven wear could indicate alignment or balance issues. Finally, assess the exhaust system for leaks or corrosion, and the underbody for rust, particularly around wheel arches and sills, as Mercedes models of this era can suffer from structural corrosion if not treated. The lack of advisories in recent tests is positive, but a thorough pre-purchase inspection will confirm whether the vehicle’s maintenance has been proactive or merely reactive.
