2004 Saab 9-3 2.0L Petrol · FX04 MZJ

This 2004 SAAB 9-3 shows a concerning maintenance inconsistency, with the most recent MOT test on 2025-06-07 passing without defects, yet the preceding test on 2025-03-10 resulted in a failure—despite no recorded issues being logged. The gap between tests (just three months) and the abrupt failure suggest either a last-minute pre-test overhaul or a critical oversight during the earlier inspection. The lack of defects in the 2025-06-07 pass does not negate the anomaly of the failed test, which implies either a temporary fix or a component that may still be underperforming. The trend is unstable, with no clear pattern of improvement or deterioration, but the most recent pass does not provide assurance of long-term reliability. The recorded mileage of 122,230 miles over 22 years equates to approximately 5,556 miles annually, which is unusually low for a vehicle of this age. The sparse MOT history—with tests clustered in March 2023, March 2024, and March 2025—suggests prolonged periods without inspection, potentially masking gradual wear. The abrupt failure in March 2025, despite the vehicle passing the previous March, raises suspicion of deferred maintenance or a component that was allowed to degrade significantly. Such low mileage could indicate the car was stored for extended periods, which may accelerate issues like battery corrosion, suspension seal deterioration, or brake fluid degradation. Given the unstable MOT history and the vehicle’s age, a buyer should prioritise an independent inspection of the suspension system, particularly the coil springs, bushes, and shock absorbers, as these components often degrade unevenly over time. The brakes, including calipers, pads, and discs, warrant close examination for uneven wear or binding, especially if the failure in March 2025 was related to braking performance. Structural integrity should also be assessed, focusing on areas prone to corrosion such as the wheel arches, sills, and subframe, as rust can compromise safety-critical elements. Finally, the electrical system—including the battery, alternator, and wiring—should be tested, as prolonged inactivity can lead to failures that may not have been evident during the recent MOT.
