1988 Mercedes-Benz 500 5.0L Petrol · F364 DOM

The vehicle presents a concerning trend of worsening mechanical and structural degradation despite passing its most recent MOT on 26 March 2026 at 152,420 miles. While the car remains legally roadworthy, the tester flagged a recurring pattern of deterioration in the braking system, suspension, and chassis. Specifically, the March 2026 test identified worn front and rear suspension arm pins or bushes, pitted front brake discs, and deteriorated brake hoses. These issues mirror advisories seen in the January 2025 and August 2023 tests, indicating that previous mechanical faults are not being proactively addressed through replacement, but are instead persisting and potentially progressing. The mileage profile suggests a vehicle that has been driven very sparingly over its 38-year lifespan, averaging approximately 4,011 miles per year. The data shows extremely low usage in recent years, with the odometer moving only 43 miles between the January 2025 and March 2026 inspections. This pattern of long periods of inactivity often contributes to the specific types of degradation seen here, such as the pitting on the brake discs and the deterioration of rubber brake hoses. While low mileage is often desirable, the lack of regular movement appears to be accelerating the aging of perishable components and allowing corrosion to settle. A prospective buyer must conduct a thorough physical inspection of the integral body structure. The MOT records from 2021, 2023, 2025, and 2026 all confirm ongoing corrosion, with the 2021 entry specifically noting rust within 30cm of a mounting. Although the tester currently deems the structural rigidity as not significantly reduced, the persistence of this issue on a vehicle of this age suggests a high risk of advanced oxidation in hard-to-reach areas. The chassis and sills require close scrutiny to ensure the corrosion has not progressed beyond the level noted in the latest report. Mechanical attention should focus on the suspension and braking subsystems. The repeated advisories for worn suspension arm bushes and pitted brake discs suggest that the vehicle is due for a significant overhaul of its consumables to prevent future failures. The deterioration of the brake hoses is a particular point of interest, as rubber components can perish and crack when left stationary for extended periods. Any buyer should budget for the replacement of these suspension bushings, brake discs, and hoses, alongside a professional assessment of the exhaust system following the minor leaks noted in 2021 and 2023.
