2011 Mercedes-Benz B-Class 1.5L Petrol · L123 ADL

The vehicle is currently roadworthy, having passed the MOT on 2025‑09‑30 at 83,825 miles with no recorded defects. However the preceding test on 2025‑09‑23 at 83,815 miles failed due to fractured rear coil springs on both offside and nearside (5.3.1(b)(i)). The failure was rectified before the subsequent pass, but the recurrence of coil‑spring damage—first noted in 2021—indicates a persistent suspension issue that warrants close attention. Overall the maintenance trend shows an improving pattern after the cluster of failures between 2021 and 2023, yet the recent coil‑spring fault suggests the suspension system may need ongoing monitoring. Mileage progression over the car’s life reflects low average usage at roughly 5,600 miles per year, which is modest for a 2011 model. The record contains a pronounced jump from 75,485 miles in October 2023 to 89,390 miles in September 2024, an increase of nearly 14,000 miles in eleven months. The following entry for September 2025 shows 83,825 miles, a reduction that points to either a mileage rollback or a data inconsistency. Earlier annual increments were modest, indicating periods of light use, but the anomalous rise and fall raise questions about the accuracy of the logged mileage. A prospective buyer should inspect the rear coil springs for cracks or improper seating, and examine the rear brake pipe for corrosion or grease contamination as previously recorded. Brake discs and calipers should be checked for binding or uneven wear, and the hand‑brake mechanism tested for proper operation. Tyre condition remains a priority; look for ply damage, uneven wear, and ensure the spare tyre is present and correctly inflated. A visual survey for chassis rust, exhaust leaks, and any signs of repair work will help confirm the vehicle’s true service history and the legitimacy of the mileage figures.
