2020 Mercedes-Benz A 1.3L Petrol · WN20 WGC

The most recent DVSA MOT test on 20 July 2026 resulted in a pass, with two advisories recorded against the rear tyres for slight cracking or perishing. These advisories are minor in nature and do not indicate an immediate failure risk, but they do flag the early stages of rubber degradation, which is worth monitoring. Reviewing the four-year MOT history, the vehicle has consistently passed its annual test without any structural, braking, suspension, or emissions failures, suggesting that the overall maintenance trend is broadly stable. However, there is a clear pattern of recurring tyre advisories across every test, which points to either a usage characteristic that accelerates rear tyre wear or an environmental factor promoting sidewall perishing. The single failure event on 15 July 2025 was directly related to cuts in both rear tyres reaching the ply or cords, a serious safety issue that was resolved before the same-day pass. At 77,982 miles over approximately six years, this Mercedes-Benz A-Class has accumulated around 13,000 miles annually, which is noticeably above the UK average for a car of this age. This higher-than-average usage implies greater wear on consumable components such as brake pads, brake discs, clutch (if applicable), tyres, and suspension bushes. The consistent year-on-year mileage progression visible across the MOT records suggests the vehicle has been in regular use rather than left standing for prolonged periods, which is generally favourable for avoiding issues such as seized brake calipers, flat-spotted tyres, or 12V battery degradation. Nevertheless, the elevated mileage warrants closer attention to high-wear items that may now be approaching replacement thresholds despite not yet failing an MOT. The recurring tyre advisories are the most significant item in the MOT history and warrant careful attention during a pre-purchase inspection. Both the nearside and offside rear tyres have been flagged for cracking or perishing across multiple consecutive tests, suggesting that the rubber compound may be hardening due to age, UV exposure, or prolonged high-mileage use. During a test drive, listen for any increase in road noise from the rear, which can indicate uneven or accelerated wear, and visually inspect both inner and outer tread edges for feathering or chamfering, particularly as edge wear was also flagged on the front tyres in 2025. Given the recurring nature of these advisories, any replacement tyres should be of a reputable brand and ideally a harder-wearing compound suitable for the vehicle's driven duty cycle. The 2025 failure for excess ply-exposed cuts should also prompt a physical inspection of the current rear tyres for any embedded debris, kerbing damage, or bulges that could compromise integrity. Beyond the recorded MOT items, a prospective buyer should carry out several age-and-mileage-appropriate checks before purchase. With nearly 78,000 miles on the odometer, the brake discs and pads should be physically inspected for wear, as Mercedes-Benz discs are prone to lipping and the caliper sliding pins can seize, leading to uneven pad transfer. The suspension should be examined for worn anti-roll bar bushes, drop links, and coil spring fatigue, which is common on this platform and can manifest as a clonking noise over speed bumps or uneven tyre wear. Fluid servicing history should be verified, particularly for brake fluid (which degrades hygroscopically every two years regardless of mileage), engine coolant, and the automatic transmission fluid if applicable. Finally, given the car's regular use pattern, the 12V battery state-of-health should be tested, as Mercedes-Benz vehicles are particularly sensitive to voltage drops which can trigger spurious warning lights and electronic module faults.
