2016 Mercedes-Benz B-Class 1.5L Diesel · SL16 OWB

The most recent MOT, carried out on 17 March 2026, resulted in a full pass with no recorded defects, and the preceding five-year record shows a consistent series of passes with no advisories or failures. This uninterrupted clean history indicates a stable maintenance regime, suggesting that the vehicle has been kept in good mechanical order and that any servicing required has been addressed promptly. There is no evidence of a deteriorating trend, and the absence of recurring faults points to a well‑maintained chassis and power‑train. At ten years old the B‑Class has accumulated 38 622 miles, averaging roughly 3 860 miles per annum – markedly below the typical UK average of 7‑10 000 miles per year for a vehicle of this age. Such low annual mileage often reflects either infrequent use or periods of extended storage. While reduced wear on consumables such as brake pads, clutch components and tyre tread is a benefit, prolonged standing can introduce age‑related issues that are not mileage‑dependent, including rubber hardening, corrosion of metal parts and degradation of fluids. Given the clean MOT record and modest mileage, the buyer should focus on age‑related inspections. Examine the tyre sidewalls for cracking, dry rot or hardening, especially if the tyres are original; even with low mileage, rubber can perish after a decade and may need replacement regardless of tread depth. Check the 12 V battery for sulphation and capacity loss, as batteries left idle for long periods often fail to hold charge and may require testing or replacement. Inspect the under‑carriage and wheel arches for any signs of corrosion, particularly around the suspension mounting points, brake caliper pins and exhaust system, as moisture can accumulate when a vehicle sits for extended periods. A thorough visual and tactile inspection of the suspension components is advisable; look for cracked or collapsed rubber bushes, worn coil‑spring mounts and any play in the ball joints or tie‑rod ends, which can develop silently over time. Verify that the brake discs are free of surface rust, pitting or uneven wear, and that the calipers move smoothly without binding – a common issue in cars that have not been driven regularly. Finally, confirm that all fluid reservoirs (engine oil, coolant, brake fluid and power‑steering fluid) have been changed in accordance with the manufacturer’s calendar intervals, as fluids degrade with age even when mileage is low; a fresh oil change and coolant flush are prudent preventative measures before committing to purchase.
