2017 Mercedes-Benz C 2.1L Diesel · AF67 WMM

The most recent MOT test on 2026-07-13 resulted in a clean pass, marking the vehicle’s most recent inspection without any recorded defects. Over the past four years, the car has consistently passed its MOTs with only a few advisories, suggesting a generally stable maintenance record rather than a worsening trend. The single advisory from 2023—slight play in the nearside front lower suspension arm ball joint—was not repeated, and the 2024 and 2025 tests showed no further issues with suspension or braking components, indicating that while minor wear is present, it has not progressed to critical levels. The absence of repeated failures or major defects in recent years lends confidence that the vehicle’s structural and functional integrity remains sound, though the owner should remain vigilant regarding the recurring brake and suspension advisories to prevent escalation. The recorded mileage of 53,317 miles for a 2017 Mercedes-Benz C-class at this point is unusually low for its age, averaging just 5,924 miles annually—a rate that is significantly below the typical wear patterns for vehicles of this generation. Such low mileage often suggests periods of prolonged inactivity, which can accelerate wear in several critical areas. For instance, standing brakes may lead to corrosion on brake discs and calipers, causing binding or reduced braking efficiency, while suspension components exposed to moisture can degrade bushings or seals faster than under dynamic use. Additionally, fluids like brake fluid and differential oil degrade over time even when the vehicle is stationary, so the vehicle’s age and low mileage profile necessitate careful attention to calendar-based maintenance rather than mileage-based servicing. The 2024 failure, which highlighted severe tyre damage, may also hint at either infrequent use with long periods of static wear or, conversely, improper storage conditions that allowed debris to accumulate on the tyres. To proceed with a thorough inspection, the prospective buyer should prioritise checking the brake system for signs of corrosion or binding, particularly on the rear brakes where thin pad wear was noted in 2024. Listen for a grinding noise when applying the brakes, which could indicate metal-to-metal contact from worn pads or warped discs. Inspect the rear brake discs for uneven wear or corrosion, and verify that the calipers are not seized or stuck. During a test drive, monitor for a soft or spongy brake pedal, which may signal fluid degradation or air in the system, and check for pulsation or vibration that could signal warped discs or binding calipers. The suspension advisories from 2023 should prompt a closer inspection of the front lower suspension arms, focusing on the ball joints for excessive play or signs of wear. Clunking noises from the front or rear suspension during cornering or over bumps are clear indicators of failing suspension components, and the buyer should also check for uneven tyre wear patterns, which could suggest misalignment or suspension issues. Beyond the mechanical checks, the vehicle’s age and low mileage make it essential to address potential issues related to static wear and fluid degradation. Begin by examining the tyres for sidewall cracking or perishing, which can occur even with low mileage if the vehicle has been stored in harsh conditions or exposed to prolonged sunlight. Check the tyre tread depth for any signs of uneven wear, particularly on the inner and outer edges, which may indicate alignment or suspension problems. Inspect the battery terminals for corrosion or loose connections, as standing vehicles can lead to sulphation or terminal oxidation, reducing battery life. A simple load test or multimeter check can confirm the battery’s health, especially if the vehicle has been unused for extended periods. Finally, consider the condition of the engine oil, transmission fluid, and differential oil, as these fluids should be replaced according to calendar intervals rather than mileage. A visual inspection for fluid contamination or sludge buildup, along with a check of fluid colour and consistency, will help determine if servicing is required. Additionally, the owner should verify that the service book has been updated, as the absence of recorded maintenance records for a vehicle of this age and mileage could indicate missed opportunities for preventative care.
