2004 Toyota Yaris 1.0L Petrol · WD04 BNZ

The vehicle presents a concerning roadworthiness profile with a clear trend of worsening structural degradation. While the car passed its most recent MOT in December 2023 at 127,811 miles, it had initially failed that same test due to critical excessive corrosion on the rear outer structure and chassis sills. The fact that it passed after a failure affecting structural integrity suggests significant repairs were theoretically made, yet the presence of general underside corrosion on the axle and coil springs indicates that the underbody is reaching a terminal stage of decay. At 22 years old, the recorded mileage of 127,811 miles is notably low, averaging approximately 5,800 miles per year. The data shows consistent but infrequent usage, with only 2,873 miles covered between the December 2022 and December 2023 tests. This low mileage has not protected the vehicle from environmental damage; in fact, long periods of standing or low-speed driving often accelerates the corrosion of older metal components, which is consistent with the recurring rust issues noted on the sills and chassis. A buyer must conduct a thorough physical inspection of the inner sills and rear mounting points to verify the quality of the rust repairs following the December 2023 failure. The history shows persistent issues with worn anti-roll bar linkages and axle swivel pins, which have been flagged across multiple years without definitive resolution. Attention should also be paid to the front shock absorbers and rear coil springs, as both showed documented signs of corrosion that could lead to sudden fatigue failure.
