1986 Mercedes-Benz 420 4.2L Petrol · D825 ASX

The vehicle maintains a high standard of roadworthiness with a consistent record of clean MOT passes over the last five years. The most recent test conducted in June 2025 at 95,444 miles resulted in no defects or advisories, indicating that the mechanical and safety systems are currently meeting all regulatory requirements. This stability suggests a proactive maintenance approach where the owner has addressed potential issues before they could result in a formal test failure. The mileage pattern is exceptionally low for a forty-year-old vehicle, averaging approximately 2,386 miles per year. Between September 2020 and June 2025, the car covered only 6,173 miles, reflecting infrequent use or long periods of storage. The intervals between tests are regular, with a 1,458 mile gap between 2023 and 2025. While this low mileage reduces wear on drivetrain components and brake pads, it increases the risk of perished rubber seals, fluid degradation, and brake-related corrosion due to lack of movement. Given the clean digital history, a physical inspection should focus on the inherent effects of long-term standing rather than mechanical wear. A buyer must examine the structural integrity of the chassis and floor pans for hidden corrosion, which often goes unnoticed on classic vehicles of this era. The suspension bushes and rubber boots should be checked for cracking or tearing, as these components degrade over decades regardless of mileage. Additionally, checking the brake lines for swelling or perished hoses is essential to ensure the low usage hasn't led to internal failure of the hydraulic system.
