The latest MOT test on 8 July 2026 passed, but the history reveals a fluctuating maintenance trend with recurring electrical and suspension issues. The 2026 failure for non-functioning stop, position, and headlamp circuits was rectified quickly, yet these faults suggest aging wiring or poor connections that may resurface. Structural corrosion has been a persistent concern, with front suspension arms now showing corrosion advisories and a 2024 failure for excessive sill corrosion near a rear suspension mounting. The split CV boot in 2024, if not addressed, would have led to joint failure, while the dangerous offside front tyre ply damage in 2023 indicates prior neglect. Overall, the pattern points to a vehicle requiring vigilant upkeep, with recent passes masking underlying wear. At 19 years old with 99,173 miles, the annual average of roughly 5,220 miles suggests light usage, which can be as problematic as high mileage due to prolonged standing. Low mileage often leads to deterioration of seals, gaskets, and rubber components from age rather than wear, as well as corrosion from infrequent use. The vehicle may have spent extended periods idle, increasing the risk of brake caliper binding, fluid degradation, and battery sulfation. Tyres and suspension bushes are particularly vulnerable to perishing and hardening over time, regardless of mileage. Prospective buyers should prioritise inspecting the front suspension arms for corrosion, particularly at the mounting points and wishbone areas, as the advisories indicate weakening that could progress to failure. Listen for clunks or knocks over rough surfaces, which may signal worn bushes or ball joints. The offside rear tyre shows cracking, so check all tyres for sidewall perishing, and verify the near-side front tyre’s tread depth, as it was close to the legal limit. Test all lighting circuits thoroughly, including stop lamps, position lamps, and headlamps, to ensure the 2026 electrical failures were properly resolved. Additionally, examine the CV boots for splits or insecurity, as a prior failure suggests the joint may already be contaminated. Given the age and likely periods of inactivity, assess the 12V battery health, as low mileage often shortens battery life through insufficient charging. Check for brake disc corrosion or uneven wear, which can indicate binding calipers from lack of use, and listen for dragging or juddering during a test drive. Inspect under the bonnet for fluid leaks, particularly from the power steering, coolant, and brake systems, as seals degrade over time. Verify service history for timely fluid changes, including brake fluid, which absorbs moisture and degrades regardless of mileage. Finally, examine the sills and underbody for structural corrosion, as the 2024 failure highlights a known weak point that may require professional evaluation.
