2017 Mercedes-Benz B-Class 1.5L Diesel · DA67 KLZ

The 2017 Mercedes-Benz B-Class holds a valid MOT pass dated 28 November 2025 at 72,397 miles, but the maintenance trend is clearly worsening. That same test date reveals a prior failure on the same day, exposing serious defects that were rectified before the pass was issued. Both front tyres had ply or cords exposed, a critical structural failure of the tyre carcass, and the nearside rear coil spring was fractured or broken. These are not minor consumable wear items. The coil spring fracture is a significant structural fault that directly compromises suspension geometry and ride height, while exposed tyre cords indicate the previous owner allowed tyre condition to deteriorate to a dangerous level. The fact that both front tyres failed simultaneously suggests basic upkeep was skipped for a prolonged period. All four brake discs were also flagged as worn, pitted, or scored, though not seriously weakened, pointing to a vehicle that has seen hard use or extended intervals between brake servicing. The mileage pattern tells a story of a vehicle that sat largely unused for over a year. Between the October 2024 pass at 60,687 miles and the November 2025 test at 72,397 miles, the car covered 11,710 miles in roughly thirteen months, a sharp acceleration from the prior annual average of approximately 6,800 miles. Before that, the mileage progression was steady and typical: 49,840 miles in November 2022, 53,849 miles in November 2023, and 60,687 miles in October 2024. The sudden spike in late 2025, combined with the severity of the defects found, raises the possibility that the vehicle was driven hard or neglected during a period of heavier use after sitting idle. A buyer inspecting this vehicle in person should focus on the suspension and braking components that have repeatedly drawn the tester's attention. The nearside rear coil spring was fractured at the most recent test and has presumably been replaced, but the condition of the offside rear spring and both front springs warrants close inspection for cracks, sag, or corrosion. The front tyres that failed with exposed cords have also been replaced, so the current tyre set should be checked for age, uneven wear, and correct specification. All four brake discs were flagged as worn and pitted, meaning the braking system should be examined for disc thickness, lipping, and any signs of uneven pad wear that could indicate binding calipers. Given the sudden increase in mileage over the past year, the exhaust system, fluid levels, and service history should be verified to confirm that routine maintenance has kept pace with the higher workload.
