2005 Mercedes-Benz C 1.8L Petrol · SP55 YWW

The vehicle's maintenance history shows a significant downward trend in roadworthiness, culminating in a major failure during the September 2021 test. While the vehicle passed in 2018 and 2020, the 2021 MOT at 125,245 miles revealed critical failures across multiple systems. The tester identified excessive corrosion on both front brake pipes and a serious structural issue regarding the nearside rear subframe mounting, which was noted as significantly reducing structural strength. This represents a severe escalation from the minor corrosion advisories seen in previous years. The recorded mileage of 125,245 miles over 21 years averages approximately 5,964 miles per year. This low annual usage suggests the vehicle has seen light use, but the MOT data indicates this may have contributed to issues with component degradation. The lack of significant mileage accumulation between 2020 and 2021 suggests the car may have sat for extended periods, which often exacerbates corrosion and brake seizure. The data provided ends in September 2021, meaning there is a significant gap in the testing history relative to the current date in June 2026. A prospective buyer must prioritize a thorough inspection of the chassis and subframe integrity. The 2021 failure regarding the subframe mounting and the recurring brake pipe corrosion indicate a high risk of advanced structural rot. The failure of the supplementary restraint system warning lamp in both 2019 and 2021 suggests an unresolved fault within the airbag or SRS system that requires professional diagnosis. Suspension components also require close scrutiny. The 2021 test flagged excessively worn front suspension arm ball joints on both sides, following earlier advisories for corroded coil springs and leaking shock absorbers in 2020. Furthermore, the inadequate service brake effort recorded in 2021 points to potential issues with binding calipers or a compromised hydraulic system. Given the severity of the last recorded failures, any purchase should be contingent on a professional underside inspection to confirm the extent of the corrosion.
