2018 Mercedes-Benz C 2.1L Diesel · T1 PEN

The 2018 Mercedes-Benz C has demonstrated consistent MOT compliance over its history, with no defects recorded in any of the four tests spanning from November 2021 to July 2025. The most recent inspection, conducted just ten months ago at 36,604 miles, confirms the vehicle remains roadworthy under current DVSA standards. There is no evidence of recurring advisories or major mechanical failures, suggesting the previous owner(s) adhered to basic maintenance intervals. However, the absence of defects does not preclude underlying issues—particularly in components like suspension bushes, coil springs, or brake calipers—which may not always trigger MOT failures until they reach critical thresholds. The recorded mileage of 36,604 miles over eight years equates to approximately 4,576 miles annually, a figure significantly lower than the UK average for a vehicle of this age. This suggests either minimal usage or prolonged periods of inactivity, which could impact fluid degradation (e.g., brake fluid, coolant) and tyre condition. Notably, the mileage remained static between the 2021 and 2023 tests (13,664 to 13,682 miles), indicating a potential lay-up of nearly two years. Such prolonged storage without regular servicing may have allowed for corrosion development in underbody components or accelerated wear in sealed systems like the transmission or differential. Given the clean MOT history, the primary focus for an in-person inspection should centre on wear-and-tear items that often evade detection until they reach failure points. The suspension—particularly the rear bushes and coil springs—should be examined for excessive play or cracking, as these components are prone to gradual deterioration even in low-mileage vehicles. Brake discs and calipers warrant close scrutiny, especially if the vehicle has experienced periods of disuse, as moisture and corrosion can accelerate wear. Additionally, the underbody should be inspected for signs of rust or structural compromise, particularly around the sills, wheel arches, and exhaust system, given the vehicle’s age and the potential for hidden corrosion during storage. While the MOT record provides reassurance of immediate roadworthiness, the buyer should prioritise obtaining full service history documentation to verify fluid changes, timing belt maintenance, and any previous repairs. The lack of advisories does not rule out deferred or non-MOT-related issues, such as electrical faults, minor leaks, or degraded interior components. A pre-purchase inspection by a qualified mechanic is strongly advised to assess these areas comprehensively.
