2004 Nissan Terrano 2.7L Diesel · YN54 ONR

The 2004 Nissan Terrano presents a stable and improving maintenance trend, culminating in a completely clean pass at its most recent MOT on 24 December 2025 at 137,506 miles. The absence of any recorded defects in the latest test indicates the vehicle currently meets all required safety and environmental standards. Looking back, the record shows a failed test on 14 November 2022 at 130,109 miles, yet notably, no defects were recorded for that failure. The subsequent retest on 15 November 2022 passed with no defects, suggesting the initial failure was likely an administrative or minor rectification issue rather than a significant mechanical fault. Since that point, the Terrano has passed three consecutive MOTs cleanly, demonstrating consistent upkeep. The vehicle's mileage accumulation aligns reasonably with its age, averaging roughly 6,250 miles per year over its twenty-two-year lifespan. However, the annual usage pattern reveals a distinct fluctuation. Between the December 2023 test at 134,328 miles and the December 2024 test at 134,574 miles, the Terrano covered a mere 246 miles, indicating a prolonged period of dormancy or very light local use. Mileage picked up slightly in the following year, adding 2,932 miles by the December 2025 test. Such sporadic usage can sometimes cause its own issues, like perishable rubber component degradation or brake disc corrosion from standing, despite the low overall mileage. Despite the pristine MOT record, a physical inspection remains essential for a vehicle of this age. The lack of recent advisories does not preclude the onset of age-related deterioration. A buyer should thoroughly inspect the structural integrity of the chassis and suspension mounting points, paying close attention to corrosion on a twenty-two-year-old 4x4. Check the condition of suspension bushes and coil springs for cracking or sagging, as these perish over time regardless of mileage. Brake components require careful scrutiny given the vehicle's history of standing still. Extended periods of inactivity often lead to binding calipers and surface corrosion on brake discs, which might not trigger an MOT failure immediately but compromise braking efficiency. Inspect the exhaust system for leaks and verify the condition of all tyres, looking for sidewall cracking that occurs with age rather than wear. While the MOT data implies a diligent owner who addressed the 2022 anomaly promptly, a hands-on assessment of the drivetrain and underbody is the only way to confirm the true mechanical condition.
