2015 Mercedes-Benz B 180 AMG Line D Auto 1.5L Diesel · SM65 ABF

This Mercedes-Benz B 180 AMG Line D demonstrates a stable roadworthiness trend over the past three MOT cycles, with the most recent test on 2025-05-02 at 50,649 miles resulting in a clean pass and no recorded defects. The absence of advisories or repeated failures across the last four tests—including the 2023 retest at 43,609 miles—suggests the vehicle has undergone consistent compliance with MOT standards. However, the single failure in April 2023, despite being retested just two weeks later, warrants scrutiny of whether minor issues were overlooked or hastily addressed. No structural or safety-critical components appear to have been repeatedly problematic, though the lack of advisories in recent tests means some wear may not have been formally documented. The recorded mileage of 50,649 miles over approximately 11 years—averaging around 4,600 miles annually—indicates unusually light usage for a vehicle of this age. The gap between the 2022 and 2023 tests (3,943 miles in nine months) is relatively modest, but the subsequent 1,143-mile interval between the 2023 failure and retest suggests either prolonged storage or infrequent driving. The most notable pattern is the consistent low mileage, which could imply the vehicle has spent extended periods stationary, potentially accelerating corrosion risks in components like suspension bushes, wheel bearings, and underbody panels. The absence of higher mileage intervals also means some high-mileage wear items—such as brake pads, timing belt (if applicable), or transmission fluid—may not have been serviced as frequently as recommended. Given the clean MOT history, a buyer should prioritise an in-person inspection of suspension integrity, particularly the rear coil springs and bushes, which are common failure points in this model and often go unnoticed until they degrade. The brakes, though never failed, should be checked for uneven wear or binding calipers, as the 2023 failure—though retested quickly—could hint at a marginal issue that was either corrected or masked. Corrosion is a critical concern given the low mileage; underbody panels, wheel arches, and suspension components should be examined for rust, especially around welds and fastenings. Finally, verify the service history for fluid changes (coolant, brake, transmission) and timing belt replacement, as these are often overlooked in lightly driven vehicles but can lead to catastrophic failure if neglected.
