The vehicle’s most recent MOT test on 2026-07-27 reveals a critical inconsistency: the same mileage (11,065) was recorded for both a failed and passed test on 12 December 2025, with no defects logged in either instance. This suggests either an administrative error in the DVSA system or a deliberate misreporting of mileage, as no mechanical issues were identified despite the failure. The lack of advisories or recurring faults in the record implies no documented deterioration in suspension bushes, coil springs, binding calipers, or structural integrity during the past year. However, the failure itself—without explanation—raises immediate concern over the tester’s assessment, particularly if it stemmed from undocumented emissions, exhaust leaks, or drivetrain irregularities. The recorded mileage of 11,065 over approximately three years equates to roughly 3,688 miles annually, which is unusually low for a high-performance hybrid model of this age. Such low mileage could indicate prolonged periods of inactivity, which may accelerate wear in fluids, seals, and suspension components due to lack of use. Alternatively, it might reflect deliberate underreporting to avoid higher tax bands or insurance premiums. The absence of intermediate MOT tests or service records further complicates verification, as no data exists to confirm whether critical intervals—such as brake fluid changes, timing belt inspections, or hybrid battery health checks—were addressed. The gap between the 2023 registration and the first MOT in 2025 (11,065 miles) also suggests the vehicle may have been stored or used sporadically, potentially leading to neglected maintenance. Given the lack of documented faults, an in-person inspection should prioritise verifying the integrity of the hybrid battery system, particularly the high-voltage connections and cooling integrity, as these are often overlooked in low-mileage vehicles. Examine the suspension for premature wear on bushes or dampers, which can occur even with minimal use if the vehicle has been exposed to moisture or stored on uneven surfaces. The brakes should be checked for uneven pad thickness or glazing, while the exhaust system must be inspected for corrosion or leaks, especially around flanges and catalytic converter mounts. Given the failed MOT without explanation, the emissions system—including the DPF, if applicable, and the turbocharger’s wastegate seals—should be scrutinised for silent failures that could recur. Finally, confirm the mileage accuracy against service records or receipts, as discrepancies here could indicate broader issues with the vehicle’s history.
