2021 BMW 420 2.0L Petrol · FG21 AGV

The most recent MOT test on 2026-03-09 confirms this BMW 420 remains roadworthy at 65,812 miles, with no defects or advisories recorded. The absence of failures across three consecutive tests—2024, 2025, and 2026—suggests a stable maintenance pattern, though the duplicate entry for 2025 (a passed and failed test at identical mileage) is anomalous and warrants clarification. The vehicle’s structural integrity and major systems appear to have passed inspection, but the lack of advisories in any test is unusual for a high-mileage BMW, indicating either rigorous servicing or a history of deferred maintenance that hasn’t yet manifested in MOT failures. The recorded mileage of 65,812 miles over five years equates to approximately 13,162 miles annually, which is unusually high for a premium vehicle of this age. This suggests either consistent heavy use or prolonged periods of inactivity followed by rapid accumulation. Notably, the gap between the 2024 and 2025 tests spans 12,665 miles, while the 2025 to 2026 interval covers 16,008 miles—both well above average for a car of this class. The absence of advisories or defects in these intervals may imply that critical components like suspension bushes, coil springs, or brake calipers have not yet reached failure thresholds, but the wear rate demands scrutiny. Given the high mileage and the vehicle’s age, a buyer should prioritise an inspection of the suspension system, particularly the rear coil springs and bushes, which are common wear points on BMW models with this mileage. The brakes, including rear binding calipers and front disc thickness, should be checked for uneven wear or corrosion, especially if the vehicle has experienced prolonged standing. Additionally, the exhaust system—particularly the catalytic converter and downstream pipes—should be examined for leaks or excessive corrosion, as these are often overlooked until they fail an MOT. The dual MOT entries in 2025 suggest either a retest or an administrative error, so verifying the vehicle’s full service history is essential to confirm whether any recurring issues have been addressed.
