2016 SEAT Leon 1.4L Petrol · KS66 BNB

The most recent MOT, carried out on 18 November 2025, was passed with no recorded defects, and the preceding four annual tests (2024, 2023, 2022 and 2021) also returned clean passes. This uninterrupted series of successful examinations suggests a consistent maintenance regime and no emerging mechanical failures that have been flagged by the DVSA. The absence of any advisories or failures over five consecutive years indicates that the vehicle’s key safety‑critical systems – brakes, suspension, lights and emissions – have been kept within acceptable limits, and the trend is stable rather than deteriorating. At ten years old the SEAT Leon has logged 126,999 miles, averaging roughly 12,700 miles per annum. This is above the typical 8‑10 000 miles per year seen on many small family cars, implying a relatively high level of component wear. The mileage figure does not show any large gaps that would suggest prolonged periods of storage, so the wear is likely to be continuous rather than intermittent. Consequently, consumables such as tyre tread, brake pads, disc thickness, clutch plates (if a manual) and engine oil seals will have experienced accelerated ageing, and any age‑related degradation of rubber components – for example bushings, boots and hoses – should be expected. A prospective buyer should give particular attention to the condition of the tyres. Even if the tread depth appears adequate, sidewall cracking or hardening can occur after a decade of service, especially if the car has spent time stationary. Inspect the tyre walls for any signs of dry rot, bulges or uneven wear that could indicate mis‑alignment or worn suspension bushes. Examine the front and rear suspension for any play in the ball joints, control arm bushings and shock absorbers; listen for clunks or squeaks when the car is driven over bumps. The braking system should be checked for disc rust, especially on the rear discs which can corrode when the vehicle is parked for long periods, and for any uneven pad wear that might point to binding calipers or stuck pistons. A visual inspection of the brake fluid reservoir for moisture or a dark colour, and a pressure test if possible, will reveal whether a fluid change is overdue. Given the vehicle’s age, also verify the health of the 12‑volt battery – a load test or checking the cranking voltage will show if it is nearing the end of its service life. Inspect all fluid levels and condition: engine oil should be clear and at the correct grade, coolant should be free of particulates and at the proper concentration, and the power‑steering fluid should not be discoloured. Look for any signs of oil or coolant leaks around the valve cover gaskets, oil pan and radiator hoses, as seals tend to harden with mileage. Finally, confirm that the service book contains regular oil changes, timing‑belt (or chain) service entries and any major scheduled maintenance; a well‑documented service history will greatly reduce the risk of hidden wear and provide confidence that the Leon has been cared for despite its higher mileage.
