2015 SEAT Leon 2.0L Diesel · KJ15 ADZ

The 2015 SEAT Leon has demonstrated a consistently clean MOT history, with the most recent test on 22 September 2025 at 92,231 miles resulting in a full pass and no recorded defects. This indicates a stable maintenance trend over the past year, with no evidence of recurring or escalating issues. The absence of advisories or minor faults across all five tests suggests the vehicle has likely undergone regular servicing, though this cannot be confirmed without service records. The latest MOT was conducted just under ten months ago, which is within the acceptable window for a used-car purchase, though a pre-purchase inspection remains essential to verify current condition. The recorded mileage progression shows a steady accumulation of approximately 8,385 miles per year, which is typical for a vehicle of this age. There are no significant gaps or abrupt jumps in mileage between tests, with the most recent interval covering 42 miles over four months—an unusually low increase that may indicate the vehicle has been stored or used minimally since September 2025. The consistency in mileage suggests the car has not been subjected to aggressive driving or neglect, though the low recent mileage also raises questions about its current state of use. Given the lack of recorded defects, a buyer should prioritise a thorough inspection of high-wear components that are not routinely checked during an MOT. Focus on the suspension system, particularly the condition of coil springs, bushes, and dampers, as these are not tested for wear during the MOT but can degrade silently. The brakes, while not failed in any test, should be examined for uneven wear, binding calipers, or corrosion on the discs and callipers, as these issues often develop between MOT cycles. Additionally, inspect the underbody for corrosion, especially around the wheel arches, sills, and exhaust system, as this is a common failure point for vehicles of this age. The exhaust emissions system should also be checked for leaks or damage, as these can affect performance and fuel efficiency. Finally, verify the integrity of the tyres, including tread depth and lateral wear, as the absence of MOT failures does not guarantee they have been maintained properly.
