1999 Mercedes 308 D 2.3L Diesel · T369 JDT

The vehicle presents a concerning roadworthiness profile characterized by a clear trend of progressive structural degradation. While it passed its most recent test in July 2023 at 191,732 miles, the record reveals persistent issues with the chassis and structure near key mounting points. This follows a critical failure in June 2022 where the rear sills were flagged for excessive corrosion that significantly reduced structural strength. The data suggests that while immediate repairs are being made to pass inspections, the underlying metal integrity is in a state of active decay. At 27 years old, the recorded mileage of 191,732 miles represents a consistent average average of approximately 7,100 miles per year. However, the timeline shows a significant drop in usage frequency between April 2021 and June 2022, where the vehicle covered only 332 miles in over a year. This period of low use, combined with the vehicle's age, often correlates with accelerated degradation of rubber components and the accumulation of moisture, which appears to have exacerbated the recurring corrosion issues noted in the inspection history. A buyer must conduct a thorough physical inspection of the rear sills, sub-frame, and suspension mounting points. The tester has repeatedly identified corrosion in these areas, moving from minor surface rust in 2021 to structural strength loss in 2022. The mechanical history also highlights a recurring issue with the steering rack inner joints and the offside front wheel bearing, which were flagged in 2022. Given the history of binding rear brakes and damp backing plates, the braking system should be checked for seized calipers or perished rubber hoses that have not been fully addressed in recent cycles.
