2013 Mercedes-Benz B-Class 1.8L Diesel · OY63 EBP

The vehicle currently presents a concerning roadworthiness status due to a clearly worsening structural trend. While it passed its most recent MOT in January 2026 at 91,972 miles, this followed a critical failure just three days prior. The tester initially flagged the nearside rear sub-frame as corroded and seriously weakened, a significant escalation from the previous year's report where the corrosion was noted but not yet weakened. The transition from an advisory to a structural failure indicates that the structural integrity of the chassis components has reached a point of active degradation. The mileage pattern is consistent with a 13-year-old vehicle, averaging approximately 7,000 miles per year. Records show a steady progression from 74,272 miles in early 2023 to 91,972 miles in early 2026. This low annual usage suggests the car has not been driven extensively, yet the data reveals that low mileage has not protected the vehicle from oxidation. The persistence of the sub-frame and coil spring issues over this 17,000-mile interval suggests that environmental factors or road salts are the primary concerns rather than wear and tear from use. A buyer must prioritize a thorough physical inspection of the rear sub-frame and exhaust mounting areas. The history shows recurring corrosion in these zones since at least 2023, meaning the repairs made after the January 2026 failure must be robust rather than merely cosmetic. The rear coil springs have been flagged for corrosion for four consecutive years; these should be inspected for fractures to prevent sudden failure. Additionally, the recurring issues with the offside front suspension ball joint and the distorted nearside front wheel suggest potential alignment problems or previous impact damage that continues to cause uneven tyre wear.
