2016 BMW 420 2.0L Diesel · SL66 MFV

The 2016 BMW 420 has maintained a consistent MOT history with no defects recorded across five consecutive tests, all passing without fail. The most recent inspection, conducted on 15 April 2025 at 106,006 miles, confirms the vehicle remains roadworthy under current DVSA standards. There is no evidence of recurring advisories or major mechanical failures, suggesting the car has been either well-maintained or subjected to minor issues that did not escalate to MOT failure thresholds. However, the absence of defects does not preclude the need for a thorough independent inspection, particularly for components not routinely tested under MOT regulations. The recorded mileage progression indicates an average annual distance of approximately 10,600 miles, which aligns with typical usage for a vehicle of this age. The most significant mileage jump occurred between the September 2021 (41,499 miles) and September 2022 (62,310 miles) tests, totalling 20,811 miles in under a year—a rate that, while not excessive, suggests the vehicle was actively used during that period. Earlier intervals, such as the 9,623 miles covered between September 2022 and April 2024, reflect a more moderate pace. The regularity of the MOT tests, all within the standard 12-month window, implies the vehicle was likely kept in active circulation without prolonged periods of neglect. Given the clean MOT record, a prospective buyer should prioritise an inspection of high-wear components not routinely scrutinised under MOT testing. The suspension system—particularly the condition of coil springs, bushes, and dampers—should be examined for excessive play, corrosion, or leaks, as these are critical for handling and safety but often fall outside MOT’s scope. Brake components, including calipers, pads, and discs, warrant close scrutiny, especially if the vehicle has been driven at higher mileage intervals, as binding or uneven wear could indicate underlying issues. Additionally, the underbody should be inspected for signs of corrosion, particularly around the wheel arches, sills, and exhaust system, as BMWs of this era are prone to rust progression over time. Finally, the engine bay should be checked for fluid leaks, belt tension, and the integrity of hoses, as these are common failure points in higher-mileage vehicles.
