1966 Mercedes 250 3.0L Diesel · WLC 97

This Mercedes-Benz 250 has maintained a consistent MOT pass status through its most recent tests, with no defects recorded in the November 2024 assessment at 20,454 miles. The absence of advisories or failings across three consecutive tests—spanning from March 2022 to November 2024—indicates a stable roadworthiness trend, though the data remains sparse due to the vehicle’s age and low mileage. The last test occurred just eight months ago, which is acceptable for a classic vehicle, though it does not meet the standard three-year interval for modern cars. No recurring issues suggest the vehicle has either been well-maintained or that critical components have not yet reached failure thresholds. The recorded mileage of 20,454 miles over approximately 60 years equates to an exceptionally low annual average of around 341 miles, far below typical usage patterns for a vehicle of this vintage. The minimal mileage progression—just 108 miles between the 2023 and 2024 tests—implies prolonged periods of inactivity, which could accelerate deterioration in suspension bushes, coil springs, and rubber seals due to static loading. The absence of mileage jumps or gaps between tests also raises questions about whether the vehicle has been stored properly, as prolonged standing can lead to corrosion in wheel arches, underbody components, and exhaust systems. Given the vehicle’s age and the lack of MOT defects, a buyer should prioritise an in-person inspection of structural integrity, particularly focusing on underbody corrosion given the low mileage and potential storage history. The suspension—including coil springs, bushes, and shock absorbers—should be examined for dry rot or perished rubber, as these components degrade over time regardless of mileage. Brake discs and calipers, while not flagged in tests, warrant scrutiny for uneven wear or binding, especially if the vehicle has spent extended periods stationary. Finally, the electrical system, including battery health and wiring integrity, should be tested, as classic vehicles often suffer from degraded connections or failing components after years of disuse.
