2012 SEAT Leon 1.6L Diesel · KS12 JXY

The 2012 SEAT LEON demonstrates stable roadworthiness based on its most recent MOT result, which was a pass on 2025-10-04 at 129,510 miles. No defects were recorded in this test, and the prior 2024-10-03 inspection at 124,579 miles also passed without issues. However, two consecutive failures in 2024-09-25 (124,503 miles) and 2023-07-31 (119,753 miles) occurred without recorded defects, suggesting potential unresolved minor concerns that may have been addressed. The absence of critical failures in the last 14 months indicates the vehicle has been maintained to a satisfactory standard, though the prior issues warrant scrutiny. The vehicle’s mileage of 129,510 miles over 14 years equates to an average of 9,251 miles annually, aligning with typical usage for its age. The MOT history shows consistent testing intervals, with a 13-month gap between the 2023-08-05 pass (119,821 miles) and the 2024-09-25 failure, which may reflect periods of reduced use or delayed maintenance. No significant spikes or drops in mileage are evident, and the lack of recurring defects in the last two tests suggests no systemic deterioration. However, the absence of detailed defect reports in earlier failures limits the ability to assess underlying issues. A buyer should verify the condition of the suspension system, particularly suspension bushes and coil springs, given the vehicle’s age and mileage. The braking system, including brake discs and calipers, should be inspected for wear, as repeated MOT tests without defects may mask gradual degradation. Additionally, the exhaust system and structural integrity warrant examination, as corrosion or fatigue could develop over time. While the MOT records show no immediate risks, the historical failures without detailed diagnostics recommend a thorough pre-purchase inspection by a qualified mechanic.
