A pattern of recurring tyre degradation is the primary mechanical concern identified in the recent inspection history, with the most recent test on 28 March 2026 confirming advisories for perishing and cracking on both the nearside front and nearside rear tyres. This follows a consistent trend of sidewall damage noted in the 2025 MOT, indicating that while the vehicle has passed its inspections, the rubber components are showing signs of age-related deterioration. The transition from two advisories in 2025 to three specific tyre advisories in 2026 suggests a progressive decline in the condition of the tyre sidewalls rather than a stable or improving trend. The recorded mileage of 7,698 miles for a five-year-old vehicle represents an exceptionally low usage profile, averaging approximately 1,540 miles per year. This level of infrequent operation is consistent with the observed tyre advisories, as vehicles that remain stationary for extended periods are susceptible to sidewall cracking and perishing due to lack of movement and environmental exposure. Mechanically, such low annual accumulation means that traditional wear-and-tear components like brake pads, discs, and suspension bushes may have less frictional wear than a higher-mileage equivalent, but it also increases the risk of seals drying out or rubber components degrading due to inactivity. Prospective buyers should focus their physical inspection on the condition of all four tyres, specifically looking for any further signs of sidewall cracking, bulging, or uneven tread wear that might indicate structural weakness. Because the advisories specifically mention perishing, it is important to check if the rubber feels excessively hard or brittle to the touch. During a test drive, pay close attention to any unusual vibrations through the steering wheel or a rhythmic thumping noise from the tyres, which could indicate that the perishing has led to internal belt separation or uneven surface degradation. Beyond the tyres, the low mileage and history of standing suggest a need to inspect other rubber-based components and fluid levels. While no specific leaks were recorded, the infrequent use pattern warrants a close look at the engine bay for any signs of dried fluid residue around gaskets or seals. On the road, listen for any irregular knocks or rattles from the suspension, as components like bushings can sometimes stiffen or degrade when a vehicle is not driven regularly. Ensure the braking performance is smooth and free from any pedal judder, verifying that the calipers are not binding after periods of inactivity.
