1987 Mercedes-Benz 420 4.2L Petrol · E544 MLB

The vehicle presents a mixed mechanical profile based on its DVSA MOT records and usage patterns. Over the years, it has accumulated a substantial number of tests, with the most recent being a clean pass on 2026-04-13, indicating that recent maintenance and handling have not introduced significant issues. However, the historical data reveals a series of recurring advisories, particularly around the front suspension components, which suggest a pattern of wear or corrosion that may have been addressed intermittently. The mileage of 105,167 miles, when considered against its age of 39 years, translates to an average of around 2,697 miles per year—relatively low for a vehicle of this vintage, which typically sees higher mileage with more pronounced component stress. This usage suggests the car has been driven infrequently or in a way that minimizes rapid degradation, but it also raises concerns about the longevity of parts such as bushings, bearings, and possibly the subframe. The suspension system appears to be a critical area of interest, with multiple failures recorded in the past five years. The most pressing concern is the nearside front lower suspension arm ball joint, which has shown signs of deterioration, including dust cover issues and play. On a test drive, this would manifest as noticeable play when bouncing over bumps or uneven surfaces, potentially affecting handling stability. Additionally, the central exhaust clamping points and the offside front suspension ball joint also show signs of wear, which could lead to exhaust leaks or misalignment over time. These findings underscore the importance of inspecting the overall suspension integrity and ensuring all clamping points are secure before operation. Given the vehicle’s history, it is advisable to pay close attention to the steering feel, especially when turning through tight spaces, and to monitor any unusual noises or vibrations during acceleration and braking. The low mileage compared to its age does not necessarily equate to a flawless mechanical state, particularly when multiple advisories are present. Buyers should be prepared for a thorough inspection focusing on the areas flagged in the MOT reports, and consider seeking a professional assessment to confirm the condition of the critical components before committing to purchase.
