2018 Mercedes-Benz E 1.9L Diesel · 61 RF

The most recent MOT test on 2026-03-17 resulted in a passing grade, though it carried advisories pertaining to rear tyres exhibiting signs of cracking or perishing, which are indicative of ageing rubber and potential structural degradation. Despite this, the overall maintenance trend over the past five years remains stable rather than deteriorating, with the vehicle consistently passing MOTs until the 2023 test, where a dangerous failure was recorded for front tyres showing a severe tear on both sides. This abrupt failure highlights a critical structural weakness in the front tyres, suggesting either a sudden wear event or underlying material fatigue that may have been exacerbated by previous advisories about rear tyre perishing. The fact that the vehicle passed subsequent MOTs without further tyre-related failures implies either timely intervention or that the tyre failure was isolated to a single batch or manufacturing defect rather than a widespread issue. The recorded mileage of 19,770 miles for a vehicle aged eight years represents a remarkably low annual usage rate of approximately 2,471 miles per year, which is far below the typical expectations for a car of this age and class. Such low mileage often correlates with periods of prolonged inactivity, particularly if the vehicle was stored under adverse conditions—such as exposure to extreme temperatures, direct sunlight, or poor ventilation—which can accelerate tyre degradation, fluid degradation, and material deterioration. The absence of higher mileage accumulation suggests that the vehicle has not undergone heavy or frequent use, which may have contributed to the observed tyre perishing advisories, as tyres exposed to static conditions are more susceptible to sidewall cracking due to ozone and UV exposure rather than mechanical wear. However, this low mileage also raises questions about whether the vehicle’s suspension, drivetrain, and other mechanical systems have been subjected to minimal stress, potentially masking underlying issues that might become apparent with increased use. Given the recent MOT advisories concerning rear tyre perishing and the critical failure of front tyres in 2023, the prospective buyer should prioritise a thorough inspection of the tyres, focusing on both front and rear sets. The front tyres, in particular, should be examined for any signs of further separation or tread loss, as the previous failure suggests a potential vulnerability to sudden blowouts. During a test drive, listen for unusual tyre noise or vibrations, which could indicate internal damage or uneven wear patterns. The rear tyres should be checked for consistent tread depth and any signs of lateral cracking, which may suggest underlying structural weakness. Additionally, verify that the vehicle’s wheel alignment and camber settings are correct, as misalignment can accelerate tyre wear and contribute to the observed perishing. Beyond tyres, the buyer should also inspect the vehicle’s suspension for signs of worn bushes, coil spring damage, or binding calipers, as these components can exacerbate tyre wear and contribute to handling issues. If the tyres have been replaced since the 2023 failure, ensure that the new tyres are fitted with appropriate load and speed ratings and that the vehicle’s wheel bearings and hubs are in good condition. For a vehicle of this age and usage profile, the buyer should also conduct a comprehensive physical inspection of the vehicle’s standing conditions and operational systems. Given the low mileage and potential periods of inactivity, check for signs of corrosion on the undercarriage, particularly around the wheel arches, exhaust system, and brake components, as standing water and humidity can accelerate rust formation. Inspect the brake discs and pads for signs of corrosion or binding, which can occur when the vehicle is left stationary for extended periods. The brake system should be tested for responsiveness and absence of pulsation or shuddering, which may indicate warped discs or contaminated brake fluid. Additionally, verify the condition of the 12V battery and associated electrical systems, as prolonged inactivity can lead to sulphation or terminal corrosion. Check the fluid levels in the engine, transmission, and differential, ensuring they are topped up and free from contamination, as fluids degrade over time even when not in use. Finally, review the vehicle’s service history for any scheduled fluid changes, such as coolant, brake fluid, and transmission fluid, which should ideally be replaced every 2–3 years regardless of mileage to maintain optimal performance. If the service records are incomplete, consider arranging a professional inspection to confirm the vehicle’s internal condition and address any potential issues before purchase.
