2005 Mercedes-Benz C 1.8L Petrol · MB52 MON

The most recent MOT, carried out on 29 May 2026, was passed but recorded an advisory that the rear suspension mounting area shows corrosion, though not to an excessive degree. This follows a failure on 26 May 2026 where major defects were flagged on both front lower suspension arm pins and bushings, a front track‑rod end ball‑joint with excessive play, and dangerous conditions on the rear brake disc and pads. The quick turnaround from failure to pass indicates that remedial work was undertaken, yet the recurrence of front‑suspension advisories in 2024 and the recent rear‑suspension corrosion suggest a maintenance trend that is stabilising only after significant repairs, but with underlying wear that may progress if not monitored. At 143,583 miles recorded for a 2005 model, the vehicle averages roughly 6,800 miles per year, which is modest for its age. Such a low annual mileage often points to periods of limited use or extended storage, which can be as detrimental as high mileage in terms of rubber and fluid degradation. The relatively low utilisation reduces the rate of consumable wear, but the age‑related calendar effects – tyre perishing, battery sulphation, and corrosion on steel components – become more pronounced, especially where the car may have been stationary for long intervals. A prospective buyer should give particular attention to the front suspension assembly. Inspect the lower arm bushings and ball joints for any looseness, cracked rubber, or oil seepage, and check the track‑rod ends for lateral play by rocking the front wheels while the car is lifted. On a test drive, listen for clunking or knocking over bumps and feel for any wandering or pulling to one side, which would indicate worn bushings or ball‑joints that may soon require replacement. The rear brake system also warrants scrutiny: verify the thickness of the rear pads (they should be well above 1.5 mm) and examine the rear discs for scoring, cracking or excessive rust that could compromise structural integrity. Any vibration or shudder when applying the brakes, especially under moderate pressure, should be taken as a sign that the discs may need resurfacing or replacement. Given the vehicle’s age, also examine the condition of the tyres, especially the near‑side front tyre that was previously noted with a cut; look for side‑wall cracking, tread loss, or dry rot, as ageing tyres can fail irrespective of tread depth. Check the brake pipe areas that have previously been flagged for corrosion, ensuring there is no rust, grease build‑up or signs of leakage. The battery should be tested for cranking voltage and electrolyte condition, as prolonged storage can lead to sulphation. Finally, confirm that all fluid reservoirs – engine oil, coolant, brake fluid and power‑steering fluid – have been topped up and, where applicable, replaced within the recommended service intervals, and that the service book reflects regular maintenance. Addressing these points will give a clear picture of the car’s current roadworthiness and any imminent expenditure required.
