2012 Subaru WRX STI-TP UK SYM-CAL AWD 2.5L Petrol · ST11 OFF

The vehicle most recently passed its MOT on 14 April 2026, but the overall maintenance trend is concerning and appears to be worsening. After several years of clean certificates, the vehicle suffered a significant failure in March 2026 involving a missing catalytic converter, excessive exhaust noise, and an ABS fault. While these were rectified to achieve a pass, the subsequent advisories regarding general underside corrosion and damaged valve stems suggest a decline in the vehicle's mechanical condition and a potential lack of preventative maintenance. With a recorded mileage of 40,127 miles over fourteen years, the vehicle has been used sparingly, averaging approximately 2,866 miles per year. While low mileage typically suggests reduced wear on the drivetrain and interior, in a vehicle of this age, it often indicates long periods of standing. This usage profile increases the risk of calendar-based degradation, where rubber components perish and fluids lose their chemical efficacy regardless of the distance travelled. Prospective buyers must scrutinise the underside of the chassis for the reported general corrosion, paying close attention to the sills and suspension mounting points, as structural integrity is paramount. The recent history of exhaust modifications and emissions failures warrants a thorough inspection of the exhaust system to ensure it is now compliant and free from leaks. During a test drive, listen for any irregular ticking or tapping from the engine which may relate to the valve stem advisory, and verify that the ABS warning lamp remains extinguished and the braking system operates without shudder. Given the low annual mileage and previous advisories for pitted brake discs and oil leaks, it is essential to check for binding calipers and ensure the brake discs are not heavily corroded from inactivity. Inspect all tyre sidewalls for hairline cracking or perishing, as tyres often expire by age before the tread is worn. Finally, verify the service history to confirm that engine oil and other critical fluids have been replaced according to time intervals rather than mileage, and check the health of the 12V battery to ensure it has not been depleted by prolonged standing.
