2015 Mercedes-Benz S-Class 3.0L Diesel · AE08 RON

The 2015 Mercedes-Benz S-Class presents as roadworthy with a stable maintenance trend. The most recent test on 20 September 2025 at 82,567 miles passed with no defects recorded, continuing a clean run of examinations. Prior passes on 12 September 2024 at 71,641 miles and 16 November 2022 at 57,282 miles also logged no advisories, indicating the vehicle has not shown worsening mechanical condition across its recorded history. Annual mileage sits at roughly 7,500 miles per year against the 82,567 total, which is typical for an eleven-year-old executive saloon and implies moderate, consistent use rather than harsh high-mileage operation. The records show a tight cluster between November 2023 and September 2024 where the car covered only about 7,500 miles, then a similar increment to the 2025 test. A failed test on 9 November 2023 at 64,146 miles preceded a pass four days later at 64,147 miles with no defects listed on either entry, suggesting an administrative or minor non-mechanical rejection rather than a substantive repair gap. The absence of recorded advisories across five tests means the MOT data alone raises no flags on suspension bushes, brake discs, corrosion, or exhaust emissions. A buyer should still commission a physical inspection of structural integrity and consumable wear, as the DVSA record does not capture gradual tyre or wiper degradation between tests. The clean history implies previous owners kept basic upkeep current, though the 2023 failure with no defect noted warrants a check of the test station paperwork to confirm the reason. Given the sparse but unbroken pass record, in-person checks should target underside rust, suspension arm condition, and brake caliper freedom even though none were flagged. Low annual use can allow damp-related corrosion or seized components to develop unnoticed, so a pre-purchase examination by a Mercedes specialist remains prudent despite the favourable MOT trail.
