2021 Mazda CX-30 2.0L Petrol · BU21 ACO

The 2021 Mazda CX-30 remains roadworthy based on its most recent MOT on 2026-02-12 at 63,795 miles, with no defects recorded. The maintenance trend shows stability over the past three years, as all tests—2024-03-05, 2025-02-24, and 2026-02-12—resulted in passing ratings. No recurring issues or escalating faults were flagged, indicating consistent upkeep. However, the vehicle’s high annual mileage of ~12,759 miles suggests accelerated wear on components such as tyres, brakes, and suspension, which may require closer scrutiny. The mileage progression reveals a sharp increase from 22,624 miles in 2024 to 45,901 miles in 2025, followed by 63,795 miles in 2026. This represents a 22,000-mile jump in 12 months and an 18,000-mile rise the next, exceeding typical usage for a five-year-old vehicle. Such rapid accumulation could strain consumables and mechanical systems, even if no immediate failures were detected. The absence of advisories or failures in the MOT history is positive but does not eliminate the need for a thorough pre-purchase inspection, particularly for wear-prone elements like brake discs, suspension bushes, and exhaust emissions. A buyer should prioritise checking the condition of brake components, as high mileage often correlates with increased wear on discs and calipers. Suspension systems, including coil springs and bushes, may show signs of fatigue or corrosion, especially if the vehicle has encountered rough road conditions. Additionally, the exhaust system and emissions controls should be verified, as older vehicles with elevated mileage can develop leaks or inefficiencies. While the MOT records confirm no critical issues, the vehicle’s usage pattern warrants a detailed mechanical assessment to confirm its ongoing reliability.
