2016 Mercedes-Benz C 1.6L Diesel · HX16 XCJ

The vehicle’s most recent MOT test on 2023-12-13 at 123,794 miles passed without any defects, though the preceding test in 2022-05-13 at 115,911 miles failed—unusually without recorded issues. This abrupt failure followed by a clean pass suggests either a one-off administrative error or a critical component nearing failure that was subsequently addressed. The lack of recurring advisories or defects in the last test implies no obvious ongoing mechanical degradation, but the 2022 failure raises caution about potential hidden issues, particularly in high-mileage components like suspension mounts or brake systems. The recorded mileage of 123,794 miles over a decade—roughly 12,379 miles annually—is significantly above the UK average for a vehicle of this age, indicating either consistent heavy use or prolonged periods of inactivity followed by rapid accumulation. The gap between tests (17,883 miles in 17 months) is unusually long, which could imply either neglect or a deliberate deferral of maintenance. Without intermediate service records, it’s impossible to confirm whether critical intervals for fluid changes, timing belts, or suspension servicing were adhered to. The absence of a 2021 test further complicates assessing long-term care, though the 2023 pass suggests the vehicle was brought up to standard before that date. Given the sparse MOT history, a buyer should prioritise an independent inspection of suspension components, particularly coil springs and bushes, which often fail without immediate warning. The 2022 failure—despite no recorded defects—may hint at a brake or steering issue that was either overlooked or repaired hastily. Exhaust emissions and structural integrity should also be scrutinised, as these are common failure points in high-mileage Mercedes-Benz models. Corrosion around wheel arches, sills, and underbody should be checked, as prolonged standing could accelerate rust. Tyre condition, despite not being flagged, warrants verification, as the mileage suggests they may be approaching their service life.
