MERCEDES-BENZ CLS2017 · 2.1L Diesel

The vehicle demonstrates a stable roadworthiness trend, with the most recent 2025-08-20 MOT at 113,879 miles recording no defects. Previous tests from 2023 to 2024 also showed no critical issues, suggesting consistent maintenance. However, the 2024-05-14 entry includes a failed test with no recorded defects, raising questions about procedural accuracy. Despite this, the absence of recurring faults in subsequent checks implies no systemic mechanical decline. The mileage progression reveals a sharp increase from 85,349 miles (2023) to 96,760 miles (2024), then to 113,879 miles (2025), averaging 17,000 miles annually in the final year. This exceeds the 12,653-mile average for its age, indicating higher-than-expected usage. Such rapid accumulation may accelerate wear on consumables like tyres and brake pads, though no such issues were flagged in MOT records. The sparse data between 2021 and 2023, with a 29,865-mile gap, also suggests potential gaps in maintenance tracking. A buyer should prioritise inspecting the suspension system for worn bushes or coil springs, given the high mileage, and check for brake disc warping or caliper binding, which can emerge under heavy use. Corrosion in underbody components, particularly if the vehicle was driven in coastal or salt-affected areas, warrants scrutiny. While MOT records show no structural defects, the lack of detailed advisories on exhaust emissions or drivetrain health means a pre-purchase inspection should verify these systems, as they are not routinely tested in MOTs.
