2016 Mercedes-Benz C 4.0L Petrol · CC63 NEV

The vehicle’s most recent MOT tests, conducted just six months ago on January 14, 2026, reveal a critical inconsistency: it was tested twice at the same mileage (75,298) and failed the second attempt without any recorded defects. This suggests either a procedural error in the testing process or, more likely, a deliberate attempt to pass the vehicle under less stringent conditions. The preceding clean passes in February 2025 and June 2024 indicate no recurring mechanical failures, but the January 2026 failure—despite identical mileage—raises suspicion about the vehicle’s true condition or the integrity of its MOT history. The recorded mileage of 75,298 miles over ten years aligns with typical usage patterns for this model, averaging around 7,500 miles annually. There are no significant gaps or abrupt jumps in mileage between tests, which would otherwise signal prolonged neglect or rapid wear. The most notable pattern is the identical mileage at two separate MOT tests in early 2026, a red flag that warrants further scrutiny. Without additional service records, it’s impossible to confirm whether maintenance has been consistent, but the absence of advisories or defects in prior tests suggests no obvious deferred repairs. Given the lack of documented faults in prior MOTs, a buyer should prioritise a thorough inspection of the suspension components—particularly the rear bushes and coil springs—given the model’s propensity for wear in this area. The January 2026 failure, despite no recorded issues, implies the tester may have identified subtle concerns, such as binding calipers or excessive brake disc wear, that weren’t formally logged. Corrosion in wheel arches, subframes, or exhaust systems should also be checked, as these are common failure points in older Mercedes-Benz models. Finally, verify the integrity of the exhaust emissions system, as repeated MOT tests without failings could mask underlying catalytic converter or sensor degradation. The dual MOT tests at the same mileage demand transparency from the seller regarding any unrecorded repairs or adjustments made between tests.
