2021 BMW M4 Competition Auto 3.0L Petrol · GF21 NHD

The vehicle presents a stable and clean roadworthiness profile, with the most recent MOT conducted on 27 March 2026 at 24,238 miles passing without any defects or advisories. The preceding test on 26 March 2025 at the identical recorded mileage also failed, yet the record shows no defects noted for that failure, suggesting a procedural or administrative retest rather than a mechanical fault. The 2021 BMW M4 Competition Auto has therefore demonstrated consistent compliance across its three recorded tests, with no recurring mechanical or structural issues flagged by any DVSA tester. The mileage pattern reveals a notable anomaly. Between the March 2024 test at 19,116 miles and the March 2025 tests at 24,238 miles, the vehicle accumulated 5,122 miles in approximately twelve months, which is plausible for a performance car driven regularly. However, the recorded mileage remained static at 24,238 miles across both the failed and passed tests on consecutive days in March 2025, and the current reading remains unchanged. This plateau raises the possibility of a data entry error, a replaced instrument cluster, or the vehicle having been stationary for an extended period. A buyer should verify the service book and physical condition to reconcile whether the odometer reading is genuine. Despite the clean MOT record, the M4 Competition's high-performance chassis and drivetrain demand careful physical inspection. The absence of flagged suspension wear, brake defects, or corrosion advisories in the record is encouraging, but a low-mileage performance car that has stood idle can develop seized brake calipers, perished rubber bushes, and flat-spotted tyres. Inspect the inner wheel arches and subframes for corrosion, check the condition of the run-flat tyres for age-related cracking, and confirm the operation of the adaptive suspension and electronic differential. A pre-purchase inspection by a BMW specialist is strongly recommended to validate the mechanical integrity behind this clean paper trail.
