2004 Mercedes-Benz 311 2.2L Diesel · RF04 EDU

The vehicle presents a concerning roadworthiness profile where the maintenance trend is struggling to outpace age-related degradation. While it passed its latest test in July 2025 at 38,163 miles, it had failed just one day prior due to parking brake failure and pitted brake discs across all four wheels. The history indicates that while the owner is addressing faults to pass inspections, the underlying mechanical condition is in a state of persistent decline rather than receiving proactive long-term care. The recorded mileage of 38,163 miles is exceptionally low for a 22-year-old vehicle, averaging only 1,735 miles per year. However, the significant mileage gap between July 2023 (27,687 miles) and July 2024 (33,845 miles) suggests the car may have sat stationary for long periods. This low usage likely explains the pervasive corrosion on the brake discs and the perished rubber components, as parts degrade through time and exposure rather than mechanical wear. A buyer must prioritize a thorough inspection of the structural integrity, specifically the sills and subframe mountings, which were repeatedly flagged for excessive corrosion. The 2024 failure noted significantly reduced structural strength in the nearside rear sill, a critical issue that requires monitoring for progression. Additionally, the front lower suspension arm ball joints have shown consistent play across multiple years, indicating that the steering and suspension components are nearing the end of their life despite the low mileage. The braking system requires immediate attention beyond the MOT, as recurring reports of pitted discs and imbalanced efficiency persist. The power steering rack seepage noted in 2024 also represents a potential high-cost repair point if the leak has accelerated. Given the history of cracked tyres and defective lenses, the buyer should check for dry rot and fluid failure common in vehicles that have not been operated frequently enough to keep components lubricated and clear.
