2004 Toyota Yaris 1.3L Petrol · LE04 AAJ

The most recent MOT inspection on 08 December 2025 resulted in a pass with no recorded defects, which suggests that the significant mechanical issues identified in early 2025 have been addressed. However, the overall maintenance trend shows a period of volatility rather than steady stability. The vehicle underwent a critical failure in January 2025 involving dangerous braking system defects, including a leaking brake pipe and significant brake imbalance, alongside a failing wheel bearing. While the subsequent pass indicates these high-priority safety items were rectified, the history reveals a pattern of reactive maintenance rather than proactive upkeep, particularly regarding the ongoing presence of structural corrosion. With a recorded mileage of 123,838 miles over approximately 22 years, this Toyota Yaris has averaged roughly 5,600 miles per year. This is considered low mileage for a vehicle of this age, which can be a double-edged sword. While it suggests less wear on the engine and drivetrain components, such low annual usage often implies the vehicle has spent extended periods stationary. Prolonged periods of standing can lead to accelerated degradation of rubber components, such as suspension bushes and tyre sidewalls, and can cause internal engine moisture buildup or seized braking components. The mileage profile suggests a vehicle that may have been used for short, infrequent trips rather than sustained motorway driving. A primary concern for any prospective buyer is the documented corrosion on the rear lower vehicle structure and chassis. Although the 2025 advisory states it does not currently affect overall security, corrosion is a progressive condition that can rapidly compromise structural integrity. During a test drive, you should pay close attention to the underside of the vehicle for any signs of fresh rust or weeping fluid. Furthermore, the previous failure regarding brake pipe leaks and the advisory for corroded fuel pipes suggest that the vehicle's hydraulic and fuel lines are susceptible to age-related degradation. You should inspect the engine bay and undercarriage for any signs of fluid weeping and listen for any unusual noises from the rear suspension, which could indicate that the previously noted wheel bearing issues or anti-roll bar bush wear have recurred. Given the low annual mileage, you must perform a thorough physical inspection of all perishable items. Check the tyres for sidewall cracking or perishing, which is a common symptom of age-related rubber degradation even if the tread depth remains sufficient. Examine the brake discs for heavy surface corrosion or pitting, which can occur if the car has been standing, and feel for any brake shudder or pulsation during deceleration which might indicate warped discs or binding calipers. It is also advisable to verify the service history to ensure that time-based maintenance, such as oil changes and coolant flushes, has been performed according to the manufacturer's intervals rather than just mileage, as fluids degrade over time regardless of how little the vehicle is driven.
