The vehicle’s most recent MOT test on 2025-09-05 at 31,000 miles passed without defects, indicating it currently meets the minimum roadworthiness standards. However, the preceding test in July 2024 revealed critical issues: binding rear brakes and tyres worn dangerously close to the legal limit on both sides. This suggests a pattern of deferred maintenance rather than a stable or improving trend. The absence of defects in the 2023 test implies the binding brakes and tyre wear were not present then, meaning these failures likely arose between 30,923 and 31,000 miles—an unusually low mileage accumulation for such severe faults. The 2025 pass does not guarantee these issues have been resolved; they may have been temporarily addressed without addressing underlying causes. The recorded mileage of 31,000 miles over 27 years—roughly 1,148 miles annually—is exceptionally low for a vehicle of this age, particularly given its lightweight construction and exposed mechanical components. The mileage remained static between the 2023 and 2024 tests (30,923 to 31,000 miles), a gap of nearly a year with no movement, which raises suspicion of either inaccurate odometer readings or prolonged storage. Such low usage could mitigate some wear, but it also increases the risk of stagnant fluids, seized components, or corrosion from moisture accumulation. The lack of intermediate maintenance records further complicates assessing whether critical services—such as brake fluid changes, suspension lubrication, or fuel system cleaning—have been performed. A buyer should prioritise an immediate inspection of the rear braking system, as the 2024 binding calipers indicate potential disc warping, seized hardware, or inadequate hydraulic pressure. The rear tyres, worn to the legal limit on both sides, should be checked for uneven wear patterns, which could point to suspension misalignment or worn suspension bushes. Given the vehicle’s age and low mileage, the suspension components—particularly the rear coil springs and bushes—warrant thorough examination for fatigue or corrosion. Structural integrity should also be assessed, especially around the chassis rails and wheel arches, where rust can compromise safety without obvious signs of wear. The absence of recent service history makes it prudent to verify fluid levels (brake, clutch, engine oil) and condition, as prolonged inactivity can lead to degradation.
