2016 Mercedes-Benz C 2.1L Diesel · WA16 ADU

The vehicle’s most recent MOT test on 2025-08-19—just under a year ago—shows a clean pass with no defects recorded, though it is unusual that the same test date appears twice with one marked as failed before being retested and passed. This suggests either a minor administrative oversight or a brief period of uncertainty before the car was confirmed roadworthy. The preceding MOT in 2024-08-09 also passed without issues, indicating a stable maintenance trend over the past two years. However, the lack of advisories or recurring faults does not guarantee hidden wear; high mileage at this age demands a thorough inspection of components that typically degrade incrementally, such as suspension bushes, coil springs, and drivetrain seals. The recorded mileage of 135,500 miles over a decade—roughly 13,550 miles annually—is significantly higher than average for a vehicle of this age, implying either consistent heavy use or prolonged periods of inactivity followed by rapid mileage accumulation. The gap between the 2022 and 2023 MOTs (9,229 miles in a year) contrasts sharply with the 12,841 miles covered between 2023 and 2024, suggesting variable usage patterns. While the MOT history lacks advisories, this mileage suggests accelerated wear on consumables like brake pads, tyres, and suspension components, which may not have been replaced between services. Given the high mileage and lack of recorded advisories, a buyer should prioritise an inspection of the suspension system, particularly the condition of rear wheel bearings and front/rear suspension bushes, which often degrade before showing obvious signs. The brakes—especially the rear calipers and discs—should be checked for uneven wear or binding, as high mileage can lead to inconsistent friction material thickness. Structural integrity, including underbody corrosion around the sills and wheel arches, should also be assessed, as rust can compromise the chassis over time. Finally, the drivetrain, including the automatic transmission fluid and differential levels, warrants scrutiny, as fluid degradation is common at this mileage.
