2011 Mercedes-Benz SLK 1.8L Petrol · D25 SEG

The vehicle’s most recent MOT on 2026-03-12 at 146,979 miles recorded a pass with no defects, indicating a stable maintenance trend. Previous tests from 2025 to 2023 also passed without issues, suggesting consistent upkeep. However, a failed test on 2023-09-12 at the same mileage as a subsequent pass raises questions about potential unresolved concerns, though no defects were documented. The absence of recorded faults in recent years implies no critical mechanical failures, but the 2023 failure warrants scrutiny for possible underlying issues. Mileage progression shows a steady annual average of ~9,800 miles, aligning with typical usage for a 15-year-old vehicle. The gap between the 2023-09-12 tests (one pass and one fail) at identical mileage suggests either a procedural error or a minor fault addressed swiftly. No significant gaps or spikes in mileage are evident, indicating regular use without prolonged inactivity. The clean record from 2024 onward implies no major systemic problems, though the lack of detailed defect reports limits insight into minor wear patterns. A buyer should inspect suspension components, particularly rear coil springs and bushes, which are common wear points in this model. Brake discs and calipers should be checked for uneven wear or corrosion, as these can develop without triggering MOT failures. The exhaust system and underbody should also be examined for rust, as corrosion often progresses unnoticed. While the MOT history shows no critical issues, the 2023 failure and absence of detailed defect data mean a physical inspection is essential to confirm the vehicle’s mechanical integrity.
