2005 Saab 9-3 2.0L Petrol · SM55 HWS

The most recent MOT test for this 2005 SAAB 9-3 was conducted on 2024-09-23 and resulted in a clean pass, marking a significant improvement over the vehicle’s previous test history. While earlier failures in 2022 and 2021 highlighted persistent issues with brake hose corrosion, CV joint boot failures, anti-roll bar ball joints, and brake binding, the 2024 test shows no such defects, suggesting either proactive maintenance or a shift in underlying component condition. However, the 2023 and 2024 failures—particularly the severe corrosion and hose failures on the front and rear braking systems—indicate a history of neglect or exposure to harsh environmental conditions, which could still pose risks if not addressed. The absence of failures in the last test does not erase the need for vigilance, as some defects may have been rectified but could re-emerge if not serviced. The recorded mileage of 90,607 miles for a vehicle aged 21 years represents an unusually low annual usage rate of approximately 4,315 miles per year, which is far below the average for its class. Such low mileage often correlates with prolonged periods of inactivity, particularly if the car has been stored in conditions prone to corrosion—such as damp garages or outdoor parking—without regular checks. The suspension, brakes, and drivetrain components, which typically wear more aggressively with higher mileage, may have been spared significant stress, but this also raises concerns about potential hidden damage from standing. For example, brake discs and calipers may have developed corrosion or binding from prolonged idling, and suspension bushes or dampers could be degraded internally despite the absence of visible wear. Additionally, fluid degradation over time, such as in the hydraulic braking system or coolant, could be exacerbated by infrequent use, leading to stiffness or failure when the vehicle is eventually driven. Given the vehicle’s age and the history of recurring advisories and failures, the buyer should conduct a meticulous physical inspection to address critical wear and potential safety risks. Front and rear brake systems remain a major concern, with past MOT failures indicating severe corrosion and hose failures. On a test drive, listen for uneven brake pedal travel, sponginess, or a grinding noise during deceleration, which could signal binding calipers or warped discs. Inspect the brake hoses for bulges, cracks, or leaks around the ferrule connections, and check for excessive brake fluid contamination, which may require a hydraulic brake fluid flush. The CV joint boot failures from 2021 and 2022 suggest the drive shafts require immediate attention; look for oil leaks around the boot seals and listen for clunking noises when accelerating or turning, which could indicate joint wear or seal failure. The anti-roll bar ball joints , also previously major failures, should be checked for excessive play or grinding when cornering, as these components can fail suddenly and cause handling instability. For the remaining systems, the buyer should verify the suspension integrity , particularly the rear shock absorbers, which had top mount failures in 2021 and 2023. On a test drive, note any excessive body roll, bottoming out on bumps, or a loss of spring rate, which could indicate failed dampers or broken strut mounts. The tyres are a critical area given the past tear failures; ensure all four have tread depths above 3mm, and visually inspect for bulges, cracks, or signs of separation, especially on the sidewalls, which may indicate structural weakness. The exhaust system should be checked for leaks, as past advisories suggest potential emissions issues; listen for hissing noises or unusual noises from the catalytic converter, and ensure no exhaust gases are leaking into the cabin. Finally, given the low annual mileage, the vehicle’s battery health and fluid condition are worth prioritising. Start the engine and check for electrical gremlins—such as dimming lights or a slow crank—before testing the battery voltage. For fluids, inspect the coolant, oil, and brake fluid for discolouration or contamination, and consider a full fluid top-up and flush if necessary, as these degrade over time regardless of usage. If the vehicle has been stored for extended periods, a thorough inspection of the corrosion-prone areas , such as the undercarriage, wheel arches, and brake components, is essential to prevent further deterioration.
