2005 Mercedes C 2.1L Diesel · DA55 TYS

The vehicle currently holds a roadworthy status, having passed its most recent MOT in October 2025 at 156,998 miles with no recorded defects. The maintenance trend shows an improvement following a period of significant advisories in 2024. While the 2024 test flagged multiple mechanical and structural concerns, the clean sheet from the subsequent test suggests that the previous owner addressed the identified faults regarding the suspension and braking system-lines. At 156,998 miles over 21 years, the car has averaged approximately 7,500 miles per year, which aligns with typical usage for a vehicle of this age. The pattern remains consistent, with intervals of roughly 6,000 to 9,000 miles recorded between annual tests from 2021 through 2025. This steady accumulation suggests the vehicle has been used regularly rather than sitting for long periods, which often helps prevent the premature degradation of rubber components and seals despite the age of the Mercedes. A buyer should focus their in-person inspection on the rear suspension and braking system. The 2024 record specifically highlighted corrosion on the nearside rear brake pipe, coil spring, and both upper suspension arms. Although these passed the 2025 test, the presence of corrosion on structural suspension components is an indicator of future rust-related failures. The buyer must also check the offside front suspension arm ball joint, which showed signs of play in 2022, to ensure no new wear has developed in that component. Tyre maintenance appears as a recurring issue, with advisories in both 2022 and 2024 for tyres worn to the legal limit or showing uneven wear. This indicates potential alignment issues or a tendency to run consumables until failure. Given the age of the vehicle, a thorough check of the underbody for structural integrity is essential to ensure that the corrosion noted in previous years has not progressed into significant thinning.
