2020 Mazda 3 2.0L Petrol · DX69 FOM

The 2020 Mazda 3 presents a stable and improving maintenance trend, culminating in a fully clean MOT pass on 12 February 2026 at 66,063 miles. That most recent test recorded zero defects or advisories, indicating the vehicle met all roadworthiness standards without any flagged items. The trajectory from the February 2024 cycle, where multiple tyre and brake advisories appeared, to the spotless 2025 and 2026 results suggests the previous owner addressed those issues promptly and has maintained the car consistently since. The vehicle has covered approximately 11,010 miles per year over its six-year life, which is typical for its age and indicates regular daily use rather than prolonged standing. The mileage progression is steady and unbroken, moving from 43,530 miles on 1 February 2023 to 57,491 miles on 5 February 2024, then to 61,833 miles on 31 January 2025, and finally to 66,063 miles on 12 February 2026. There are no suspicious gaps or sudden jumps in the odometer record, and the MOT testing intervals align with annual cycles, confirming the car has been kept in active, consistent service. The February 2024 test cycle is the only period where defects appeared, and they centred on consumable wear items rather than structural or mechanical failure. Front brake pads were flagged as wearing thin, and all three tyres assessed that day were either at or approaching the 1.6mm legal minimum tread depth. The TPMS warning light was also illuminated, which typically indicates a tyre pressure discrepancy rather than a component fault. These are routine wear items for a car covering 11,000 miles annually, and the fact that none of these issues recurred in the 2025 or 2026 tests confirms they were rectified rather than neglected. A buyer should still inspect the front brake pads and discs for even wear, check all four tyres for uneven tread patterns that could indicate alignment or suspension geometry issues, and verify the TPMS system resets correctly after inflation. Beneath the car, examine the subframe, sills, and suspension mounting points for corrosion, particularly around the rear trailing arms and front lower wishbone bushes, as these are common corrosion points on Mazda 3 models of this generation. The clean recent MOT record is encouraging, but a physical inspection of the undercarriage and a test drive over varied road surfaces will confirm whether the suspension and steering remain tight and free from play.
