1998 Mazda 121 1.3L Petrol · S284 AEJ

The 1998 Mazda 121 last failed its MOT on 28 July 2022 at 21,314 miles and has not been tested since, leaving it off the road for nearly four years. The maintenance trend is clearly worsening. In the July 2021 pass at 20,410 miles the tester noted sub-frame and Macpherson strut corrosion as present but not seriously weakened; by the July 2022 failure the same sub-frame was corroded and seriously weakened, and the outer and inner sills, rear structure behind the struts, and offside front body were all corroded to the point of significantly reduced rigidity. Structural integrity was lost across multiple load paths in under twelve months. Recorded mileage shows light use for a 28-year-old vehicle, rising from 18,618 miles in August 2019 to 21,314 miles by July 2022, an average of roughly 900 miles per year. The gap between the 2022 failure and today spans four years with no further test, implying the car has stood unused or untaxed since. Low annual mileage masked little: corrosion advanced regardless of distance covered, and the 904-mile increase between 2021 and 2022 did not prevent a cascade of structural and mechanical failures. A buyer must treat this vehicle as structurally compromised rather than cosmetically tired. The July 2022 test flagged a seriously weakened front sub-frame, fractured near-side anti-roll bar mounting, insecure driver's seat on a corroded floor, and both rear coil springs corroded. The tester also recorded excessive corrosion on the near-side brake pipe by the fuel tank, poor parking brake efficiency, and a loose exhaust heat shield. These are not consumable items. In person, the buyer should probe the outer and inner sills, rear chassis legs behind the struts, and sub-frame with a calibrated hammer to judge remaining metal thickness. Verify the driver's seat mount and floor pan, inspect both front CV boots which were perished in 2021, and confirm whether the brake pipes and rear coil springs have been replaced. Given the four-year dormancy and the severity of the last failure, a full structural assessment by a bodyshop is warranted before any road use.
