2015 Mercedes-Benz B-Class 1.5L Diesel · WF15 CME

The 2015 Mercedes-Benz B-Class presents a stable and clean roadworthiness profile. The most recent test on 28 January 2026 at 74,876 miles returned a pass with no defects recorded, continuing an unbroken sequence of five consecutive annual passes with zero advisories or failures since January 2022. Annual mileage sat well below the typical average for much of the car's life. The January 2022 test logged 29,604 miles, rising to 42,918 by January 2023, 48,199 by January 2024, and 55,092 by January 2025. That equates to roughly 8,000 to 13,000 miles per year through this period. A sharp jump then occurred between January 2025 and January 2026, with 19,784 miles added in twelve months, nearly tripling the prior year's rate and bringing the total to 74,876. The DVSA record itself is sparse, showing no flagged corrosion, suspension wear, brake defects, or emissions concerns across the entire history. Given the absence of any recorded advisories, the previous owner clearly kept the vehicle to a standard that satisfied each examiner without raised concerns on tyres, brake discs, coil springs, or structural integrity. A clean sheet across five tests suggests disciplined servicing rather than deferred consumable replacement. A buyer should still commission a physical inspection despite the spotless record. The sudden 19,784-mile surge in the last year points to heavier use that may have accelerated clutch, drivetrain, and suspension bush wear not yet visible to the MOT regime. Verify service history for that period, check underneath for early corrosion, and confirm brake caliper operation and tyre sidewall condition before purchase.
