2003 Honda Jazz 1.3L Petrol · LM52 CGF

Significant structural and fluid-system corrosion presents a progressive risk to the long-term viability of this vehicle. The most recent MOT test on 29 October 2025 confirms a worsening trend of degradation, specifically regarding the vehicle's underbody integrity and fuel delivery systems. While the car passed its latest inspection, the accumulation of advisories concerning corroded inner and outer rear sills, a corroded rear axle, and deteriorating fuel and brake pipes indicates that the rate of oxidation is accelerating. The presence of a non-excessive oil leak alongside these structural concerns suggests a vehicle that is reaching a stage where multiple simultaneous repairs to the chassis and hydraulic lines may be required to maintain roadworthiness. The recorded mileage of 148,280 miles over approximately 23 years equates to an average annual usage of roughly 6,447 miles. This represents a relatively low-intensity usage pattern for a vehicle of this age, which often implies less frequent exposure to the high-speed motorway driving that can help clear exhaust systems and prevent certain types of buildup. However, in the context of the documented corrosion, this lower annual mileage may also suggest the vehicle has spent significant time in environments where moisture and road salt can settle on the chassis without the drying effect of regular, heavy use. This usage profile aligns with the observed deterioration of the sills, axle, and brake lines. Prospective buyers must pay close attention to the integrity of the braking and fuel systems during a physical inspection. The recurring advisories for a corroded nearside rear brake pipe, which was noted as being covered in grease or other material, suggest a need to verify if this was done to mask the extent of the decay. On a test drive, listen for any changes in brake pedal feel, such as a spongy sensation or a lack of firmness, which could indicate internal degradation of the brake hoses or pipes. Additionally, check for any irregular idling or hesitation under acceleration, which might stem from the documented fuel pipe corrosion affecting fuel pressure. The structural advisories regarding the rear sills and the rear axle require a thorough visual inspection of the underside, ideally using a ramp or a creeper. Look for significant scaling or perforation in the metalwork, particularly where the sills meet the rear wheel arches. During the test drive, pay close attention to the rear suspension performance; any knocking, clunking, or unsettling movements when traversing uneven surfaces could indicate that the corrosion on the rear axle or related mounting points is affecting the vehicle's structural rigidity or suspension geometry. The reported oil leak should also be located to determine if it is a simple gasket issue or if it is contributing to the degradation of nearby rubber components.
