The most recent MOT test conducted on 13 April 2026 resulted in a pass, but the overall maintenance trend is showing signs of gradual decline. While the 2024 inspection was entirely clean, the two subsequent tests in 2025 and 2026 have both flagged identical advisories regarding oil misting on both the nearside and offside rear shock absorbers. This indicates a persistent and likely progressing seal failure that has remained unaddressed, suggesting a reactive rather than proactive approach to the vehicle's suspension maintenance. The vehicle has recorded 12,445 miles over approximately five years, averaging roughly 2,489 miles per year. This is significantly lower than the typical UK annual average for a crossover of this age. While this low mileage implies minimal wear on the engine internals and drivetrain, it introduces specific mechanical risks associated with vehicle stasis. Infrequent use often leads to the degradation of rubber components and can cause moisture build up or corrosion in areas that would otherwise be kept clear through regular heat cycles and consistent movement. The recurring advisories regarding the rear shock absorbers require close attention during the pre-purchase inspection. Oil misting is a primary indicator of hydraulic fluid escaping the damper body, which eventually compromises the vehicle's ability to control wheel oscillation. During a test drive, the buyer should listen for knocks or clunks when traversing uneven road surfaces and observe if the rear of the vehicle exhibits excessive bouncing or instability after hitting a bump. While these are currently advisories, these components will eventually fail the MOT once the leak becomes significant, necessitating the replacement of both rear dampers to ensure balanced handling and braking stability. Given the low annual usage, a comprehensive physical inspection is essential to supplement the MOT history. The buyer should carefully examine the tyre sidewalls for fine cracking or perishing, as rubber degrades with age regardless of remaining tread depth. The health of the 12V battery should be verified, as infrequent use can lead to premature sulfation and failure. Furthermore, the brake discs should be inspected for heavy surface corrosion or binding calipers resulting from long periods of standing. Finally, the service history must be scrutinized to ensure that oil and filter changes have been performed based on calendar intervals rather than mileage, as engine oil degrades through oxidation over time.
