2005 Mercedes C 1.8L Petrol · SD55 RFZ

The vehicle is currently roadworthy but the maintenance trend shows a worsening progression of age-related component degradation. While the most recent test on 15 May 2026 at 91,118 miles passed, it introduced several new advisories regarding worn front suspension arm bushes and a damaged track rod end. This marks a shift from the 2025 test where these specific issues were absent, indicating that the lower suspension components are now reaching the end of their functional life despite the low annual mileage. At 21 years old, the recorded mileage of 91,118 miles is significantly low, averaging approximately 4,339 miles per year. The data shows consistent low-level usage, with only 1,055 miles covered between May 2025 and May 2026. This low mileage profile explains the prevalence of rubber-based failures, such as perished tyre sidewalls and deteriorated dust covers noted in the 2024 records, which often occur when vehicles suffer from time and exposure rather than mechanical wear from distance. A buyer must conduct a thorough physical inspection of the rear sub-frame and anti-roll bar, as both components have been flagged for corrosion since at least 2023. While the tester currently describes these as not seriously weakened, the persistence of surface rust across multiple years suggests an ongoing environmental corrosion issue. The rear brake pipes also require close scrutiny; both nearside and offside lines have been noted as corroded and covered in grease for three years, which can mask deeper structural thinning of the metal pipework. The front suspension requires immediate attention due to the new May 2026 advisory on worn lower arm bushes and a corroded track rod end. Given the history of perishing and cracking tyres noted in 2023 and 2024, the current tyres should be checked for dry rot sidewall integrity. The front brake discs were also noted as worn in the latest test, suggesting that replacement is imminent in the near future to maintain braking performance.
