2021 Mercedes-Benz B 1.3L Petrol · EY21 ACF

The most recent DVSA MOT test on 8 December 2025 recorded a PASS, maintaining a clean pass history across all three recorded tests, with the previous examinations in July 2024 and December 2024 also resulting in pass outcomes with no advisories or failures. The maintenance trend therefore appears stable and consistent, with the vehicle continuing to meet the required roadworthiness standards at each annual assessment. However, the latest test introduced three tyre-related advisories concerning the nearside rear, offside rear, and nearside front outer tyres, all involving cracking, perishing, or minor cuts. While these defects were not severe enough to warrant a failure, they represent the first signs of degradation in the rubber compounds and warrant close attention from a prospective buyer. With an odometer reading of 33,953 miles on a five-year-old car, the annual mileage equates to around 6,791 miles per year, which is broadly typical for a vehicle in its age bracket and suggests neither excessive use nor prolonged standing periods. This level of usage generally implies regular operation, which is mechanically beneficial for components such as the braking system, battery, drivetrain, and seals, as it prevents the issues commonly associated with vehicles left idle for extended periods. There are no significant gaps in the mileage progression recorded, and the steady accumulation suggests consistent rather than sporadic use, allowing brake discs, pads, tyres, and suspension components to wear in a relatively even and predictable manner. Despite the clean pass history, the advisory items recorded on the rear tyres are particularly noteworthy because they indicate sidewall perishing or cracking, which is a typical age-related phenomenon affecting rubber compounds regardless of tread depth. On a test drive, listen for any uneven road noise from the rear axle and inspect the inner and outer sidewalls carefully for visible cracking, especially in the flex zone between the tread and the wheel rim. Additionally, although the front tyre advisory concerns a minor cut, it should be monitored for any progression, and all four tyres should be examined for manufacturing date codes, as tyres older than five years may suffer hardening of the compound even with adequate remaining tread. Given that the recorded mileage is moderate, verify the brake disc condition on the front and rear axles for any lipping or corrosion, particularly around the outer edges, and confirm that the handbrake holds firmly on inclines to rule out binding calipers from infrequent heavy braking. Given the calendar age of the vehicle, it is prudent to check the condition of age-sensitive items that may not be fully captured by the MOT history. The 12V battery should be tested for its state of charge and cranking performance, as batteries in vehicles of this age can lose capacity even under moderate use. Coolant, brake fluid, and automatic transmission fluid (if applicable) should be confirmed as having been replaced at the manufacturer-recommended intervals, as these fluids degrade over time regardless of mileage. Inspect the underside of the vehicle, paying close attention to suspension bushes, anti-roll bar links, and coil springs for any signs of corrosion or cracking, particularly if the vehicle has been operated in winter conditions with road salt exposure. Finally, verify that the full service history is present, ideally with main dealer or specialist stamps, to confirm timely replacement of items such as the cabin and engine air filters, spark plugs, and oil, ensuring the vehicle has been maintained to Mercedes-Benz standards throughout its life.
