2018 Mercedes Unknown 2.1L Diesel · RX68 AUF

This Mercedes-Benz has maintained a clean MOT history with no recorded defects across all five tests, including the most recent examination on 2025-09-05 at 30,256 miles. The absence of advisories or failures suggests the vehicle has consistently met UK roadworthiness standards during its service life. However, the near-identical mileage readings for the 2022 tests—13,690 and 13,691 miles—indicate a potential data anomaly rather than a mechanical issue, as the vehicle would not have undergone two tests in such close succession without movement. Overall, the trend is stable, with no evidence of recurring faults or progressive wear patterns in the official record. The recorded mileage of 30,256 miles over eight years—approximately 3,782 miles annually—is unusually low for a vehicle of this age, particularly given the typical wear patterns expected in a Mercedes-Benz. The gap between tests ranges from 364 to 368 days, adhering to the standard three-year MOT cycle, but the minimal mileage accumulation raises questions about the vehicle’s usage history. Such low mileage could imply extended periods of storage, which may accelerate degradation of fluids, seals, and rubber components if maintenance was neglected during inactivity. The lack of advisories or failures does not preclude the need for a thorough inspection of items prone to deterioration when vehicles are stood for prolonged periods. Given the clean MOT record, a buyer should prioritise an in-person inspection of high-wear items that are not routinely tested under MOT but are critical to long-term reliability. Focus on the suspension system, particularly the condition of bushes, coil springs, and dampers, as these components degrade gradually and may not always trigger MOT failures until significant wear is present. The braking system—including caliper binding, disc thickness, and pad material—should be checked for uneven wear, as binding calipers often go unnoticed until they cause noise or reduced efficiency. Additionally, inspect the underbody for corrosion, especially around the sills, wheel arches, and exhaust system, as low mileage does not guarantee rust-free conditions if the vehicle was exposed to harsh environments or stored unsafely. The absence of MOT advisories does not rule out the possibility of hidden issues such as minor fluid leaks, worn drive belts, or degraded cabin filters, which are not inspected during the test. A pre-purchase diagnostic check should also verify the integrity of the exhaust system for leaks or excessive corrosion, as emissions-related failures are uncommon in this model but can arise from prolonged neglect. Given the low mileage, attention to service history—particularly oil changes, timing belt (if applicable), and fluid condition—will be essential to confirm whether maintenance was performed as recommended.
