2009 Mercedes-Benz B-Class 2.0L Diesel · T1 HSU

This Mercedes-Benz B-Class presents a stable roadworthiness record over the past two years, with the most recent MOT on 21 March 2026 at 58,059 miles passing without any defects. The absence of advisories or failures in the last three tests—including the 25 April 2024 and 20 April 2023 passes—suggests the vehicle has been well maintained in critical areas, with no recurring mechanical or structural issues. The only anomaly is the duplicate 1 April 2025 entry, where the car was both passed and failed at the same mileage, which may indicate a clerical error rather than a genuine issue. For a vehicle of this age, the clean MOT history is unusually positive, though the lack of advisories could also imply minimal proactive checks beyond legal requirements. The mileage accumulation is exceptionally low for a 17-year-old vehicle, averaging just 3,415 miles per year , which is roughly half the typical annual mileage for a private car. The gap between the 2023 (37,922 miles) and 2024 (38,296 miles) tests—just 374 miles over 12 months —strongly suggests the car has spent long periods in storage or seen very light use. This could mean reduced wear on consumables like tyres and brakes, but it also raises questions about fluid health (oils, coolants) and battery condition, as stagnation accelerates degradation in these components. The sudden jump to 46,156 miles by April 2025 —an increase of 7,860 miles in a year —marks a shift, though even this is modest compared to average usage. Without further service records, it’s impossible to confirm if this uptick was driven by a change in ownership or usage patterns. Given the clean MOT history, a buyer should still prioritise a thorough inspection of components prone to hidden wear, particularly in a low-mileage vehicle where fluids and soft parts may have degraded from inactivity. The suspension—including coil springs, dampers, and bushings—should be checked for stiffness or leaks, as these can fail silently even with minimal movement. Brakes, despite no MOT flags, warrant closer scrutiny: inspect for uneven pad wear, glazing, or binding calipers, especially if the car has been driven infrequently. The exhaust system, while not mentioned in the MOTs, may show surface rust or loose mounts from prolonged exposure. Finally, verify all fluid levels—engine oil, brake fluid, coolant, and power steering—and check for leaks, as stagnant systems are more likely to harbour contamination or degradation. The absence of corrosion advisories is a positive sign, but a full underbody inspection for structural rust in wheel arches or sills remains advisable.
