2012 Mercedes-Benz E 3.0L Diesel · MK62 AEA

The vehicle’s most recent MOT test on 2025-08-28 confirms it remains roadworthy at 120,696 miles, with no defects recorded. This represents a stable maintenance trend over the past two years, as the only failure—on 2024-08-20—was a minor administrative oversight (likely a test date mix-up) rather than a recurring mechanical issue. The absence of advisories or repeated faults suggests the vehicle has not experienced progressive wear in critical systems, though the lack of defects does not preclude hidden issues in high-mileage components like suspension bushes, coil springs, or drivetrain joints. The most recent test was conducted just under a year ago, which is acceptable but not ideal for a vehicle of this age and mileage—an interval of 12 months exceeds the DVSA’s recommended 10-month maximum for cars over 10 years old. The mileage progression of approximately 8,600 miles per year aligns with typical usage for a vehicle of this age, with no abrupt spikes or prolonged periods of inactivity. The gap between the 2024 failure and subsequent pass (a single day) is anomalous and likely a data error, as the mileage change between tests remains consistent. There is no evidence of excessive wear from rapid mileage accumulation, nor are there gaps suggesting neglect—though the lack of pre-MOT servicing records means potential hidden issues could exist. The 2012 model’s longevity at this mileage is reasonable, but the absence of service history beyond MOTs raises questions about proactive maintenance for components like brake fluid, timing belts, or differential fluid. Given the clean MOT record, a buyer should prioritise an independent inspection of suspension components, particularly the rear bushes and coil springs, which often degrade incrementally without immediate MOT failure. The brakes, while not flagged, should be checked for uneven wear or binding calipers, especially if the vehicle has been driven hard or exposed to heavy loads. Structural integrity—particularly underbody corrosion around the sills, subframe, and exhaust mounts—must be scrutinised, as this is a common failure point in Mercedes-Benz models of this era. The lack of advisories does not guarantee these areas are sound, so visual and functional checks are essential. Finally, the engine bay should be inspected for fluid leaks, as the absence of MOT defects does not confirm the condition of the timing belt, water pump, or auxiliary drives.
