2008 Subaru Impreza 2.5L Petrol · RF08 NVM

The Subaru Impresa presents a mixed maintenance picture. The most recent test on 30 October 2025 at 109,302 miles passed cleanly with zero defects, which is a positive sign for immediate roadworthiness. However, that clean result came just eight days after a serious failure on 22 October 2025 at 109,299 miles, where the tester flagged an Offside Rear Brake pipe leaking on a hydraulic braking system, brake performance unable to be tested, and multiple exhaust emission failures including excessive carbon monoxide, hydrocarbon content, and Lambda readings outside specified limits, plus excessive exhaust noise. The fact that all these issues were rectified within a week suggests the previous owner addressed them promptly, but the severity of the October 2025 failure, particularly the leaking brake pipe, indicates a period of deferred maintenance immediately prior to the pass. The mileage pattern tells an interesting story. Between the March 2023 pass at 105,645 miles and the June 2024 failure at 107,687 miles, the car covered roughly 2,042 miles in approximately 15 months. Then between June 2024 and October 2025, it added just 1,615 miles over another 16-month period. This is remarkably low annual use of around 1,300 miles per year in recent years, well below the already modest lifetime average of approximately 6,072 miles per year. Such low annual mileage can mask underlying issues, as short trips and prolonged standing accelerate corrosion of brake components, exhaust systems, and suspension bushes compared to steady motorway use. The gap between the June 2024 and October 2025 tests is also notable, with no recorded test for over 16 months, which is unusual for a vehicle that should be tested annually. Buyers should pay particular attention to the braking system and exhaust during any in-person inspection. The October 2025 failure for a leaking Offside Rear Brake pipe raises concerns about the condition of the remaining brake lines, especially given the low mileage and potential for corrosion rather than wear. Inspect all rigid brake pipes and flexible hoses for weeping, corrosion, or perishing. The exhaust system also demands close scrutiny. The recurring emission failures across both the June 2024 and October 2025 tests, including a missing catalytic converter noted in 2024 and excessive noise flagged in 2025, suggest the exhaust may have been modified, repaired poorly, or subjected to temporary fixes. Check the catalytic converter is present and original, examine all joints and mounting points for leaks, and verify the silencer condition. The June 2024 failure also noted an inoperative Nearside Registration plate lamp, a minor electrical point worth verifying works correctly. Beyond the flagged defects, the low annual mileage warrants a thorough check of perishable components. Suspension bushes, tyre sidewalls, and rubber seals deteriorate with age and standing rather than mileage. Inspect for perished or split bushes on the front and rear suspension, check tyre date codes for age-related cracking regardless of tread depth, and examine the underside for surface corrosion on subframes and suspension mounting points. The clean pass in October 2025 is reassuring, but the severity and recency of the preceding failures mean this vehicle's maintenance history reflects a reactive rather than proactive ownership pattern. A pre-purchase inspection by a qualified mechanic is strongly recommended.
