2021 BMW 420I M Sport Auto 2.0L Petrol · CY71 KNO

The 2021 BMW 420i M Sport Auto presents as roadworthy with a stable maintenance trend. The most recent test on 11 December 2025 at 30,655 miles returned a pass with no defects recorded, continuing a clean sequence across all three available MOT entries. No advisories or mechanical faults appear at any stage, indicating the vehicle has not required corrective work within the test regime. Annual mileage sits at a modest 6,131 miles given the car's five-year age. The records show 20,397 miles on 12 August 2024, rising to 20,874 miles by 18 December 2024, then jumping to 30,655 miles at the December 2025 test. That final 9,781-mile gain in roughly twelve months marks the only period of heavier use; prior to it the car covered very little ground. The sparse three-entry history offers no evidence of neglected consumables or deferred repairs, though the gaps limit longitudinal insight into wear patterns. A buyer should still commission a physical inspection of suspension bushes, coil springs, and brake discs despite the clean MOT slate. Low-mileage BMWs left standing can develop perished rubber components and surface corrosion on structural underbody points that a pass test will not always capture. The absence of recorded advisories means no recurring fault trend exists to chase, but pre-purchase checks on tyre sidewalls and caliper freedom remain sound practice given the late mileage surge. The test data implies a previous owner who kept the car lightly used and properly serviced to MOT standard. No failing tests or repeated advisories suggest basic upkeep was not skipped. Treat the verified record as a positive baseline rather than a substitute for a independent mechanical appraisal before purchase.
