2004 SEAT Leon 1.8L Petrol · GD04 XVS

The 2004 SEAT Leon’s most recent MOT on 14 April 2026 at 116,344 miles resulted in a pass, though the test revealed multiple advisories indicating a deteriorating mechanical condition. Corrosion on the front subframe, suspension arms, and rear brake pipes persists, while brake discs across all four wheels show wear and scoring, and front brake pads are reported as wearing thin. Tyre tread is consistently close to the legal limit on all four wheels, and the exhaust system remains noisy, a recurring issue since at least 2020. These advisories suggest a gradual decline in component integrity rather than a stable or improving trend, with critical systems such as braking and structural elements requiring urgent attention. Mileage accumulation aligns with the vehicle’s age, averaging approximately 5,288 miles annually over 22 years. The recorded mileage increased steadily from 98,267 miles in December 2022 to 116,344 miles in April 2026, reflecting consistent usage. A notable gap exists between December 2020 (81,687 miles) and January 2022 (98,267 miles), during which the vehicle accumulated 16,580 miles, suggesting potential periods of higher utilisation or storage followed by renewed use. No significant spikes in mileage are evident in the records, indicating no abrupt changes in ownership or usage patterns. Prospective buyers should prioritise a thorough inspection of the braking system, focusing on disc thickness, pad wear, and the condition of brake pipes, which have shown progressive corrosion since 2020. The exhaust system’s persistent noise and emissions issues, particularly the carbon monoxide exceedances in 2024 and 2025, warrant investigation for underlying engine or catalytic converter faults. Suspension components, including the front subframe and arms, exhibit structural corrosion that could compromise rigidity if left unaddressed. Tyre condition is critical, as tread wear has repeatedly approached legal limits, necessitating immediate replacement. Additionally, the vehicle’s structural integrity, particularly around the sills and floor pans, should be assessed for hidden corrosion or damage, given the recurring advisories in these areas.
