2009 Daihatsu Sirion 1.0L Petrol · AV09 EXM

The most recent MOT inspection on 24 July 2026 resulted in a pass, but the vehicle's maintenance profile shows a concerning trend of progressive degradation in its running gear. While the car has avoided outright failures in recent years, the frequency and nature of the advisories suggest a steady decline in the condition of the chassis and suspension components. Specifically, there is a recurring pattern of deterioration regarding the suspension bushes and axle swivel pins, which have appeared as advisories consistently since at least 2021. This indicates that while the vehicle remains legally roadworthy, the mechanical integrity of the suspension system is steadily weakening and will require imminent intervention to prevent future failures. With a recorded mileage of 57,415 over approximately 17 years, this Daihatsu Sirion has been driven an average of only 3,377 miles per year. This exceptionally low annual usage suggests the vehicle has spent significant periods stationary or has been used purely for short, infrequent trips. While low mileage typically implies less wear on the engine and drivetrain, it presents specific risks for a vehicle of this age. Long periods of standing often lead to accelerated rubber degradation, such as the perished suspension bushes and cracking tyres noted in the records, and can cause fluid breakdown or internal component seizure. The low mileage does not negate the age-related wear seen here; rather, it explains the specific type of deterioration present. A prospective buyer must pay close attention to the underside of the vehicle and the suspension during a test drive. The persistent advisories for underside corrosion and corroded brake pipes, which have been documented for several years, suggest that the structural integrity of the chassis and the safety of the braking system are under threat from oxidation. During the test drive, listen for various knocking or clunking noises when traversing uneven surfaces, which would indicate that the worn suspension arm bushes and axle swivel pins are reaching the end of their service life. Furthermore, check for any pulling to one side or imprecise steering response, as the previous history of steering rack inner joint play suggests the steering geometry may be compromised. The advisories regarding tyre perishing and cracking on the offside front tyre are a direct consequence of the vehicle's age and low usage patterns. Rubber compounds naturally harden and crack over time due to UV exposure and ozone, regardless of tread depth, making the tyres prone to sudden failure. You should inspect all sidewalls for similar cracking and check the manufacture date codes to ensure the tyres are not excessively old. Given the history of brake pipe corrosion being covered in grease, it is vital to verify if this was a preventative measure or an attempt to mask significant decay. I strongly recommend a professional inspection of the brake lines and the extent of the underbody corrosion before proceeding, as these issues are progressive and will eventually necessitate costly repairs to maintain roadworthiness.
