2017 BMW 420 2.0L Diesel · AF67 YML

The most recent MOT, carried out on 17 December 2025, was passed with no recorded defects, and this clean result is consistent across the previous four annual tests dating back to December 2021. The uninterrupted succession of pass‑only outcomes suggests a stable maintenance regime, with no evidence of emerging or recurring faults that would indicate a deteriorating condition. In the absence of any advisories or failures, the vehicle appears to have been kept in a road‑worthy state throughout the period covered by the DVSA records. At nine years old the BMW 420 has logged 61 805 miles, which works out to an average of roughly 6 900 miles per annum. This figure sits comfortably within the typical UK usage range for a vehicle of its class and age, indicating neither excessive wear from high mileage nor the risk of age‑related degradation that can accompany very low‑kilometre cars which may have spent long periods idle. There are no conspicuous gaps in the MOT chronology that would hint at prolonged storage, and the mileage progression appears steady, suggesting balanced wear on the engine, transmission, and ancillary components. For a prospective buyer, the primary focus should be on age‑related items that are not captured by MOT data. Inspect the tyre tread depth and sidewall condition; even with moderate mileage, tyres can perish after six to eight years, showing cracking or hardening of the rubber that compromises grip. Examine the 12‑volt battery for signs of sulfation or reduced cranking power, especially if the car has been parked for extended periods, and consider a load test to confirm remaining capacity. Verify that the service history includes regular oil changes, coolant flushes, and timing‑chain or belt inspections in line with BMW’s service intervals, as these are critical for long‑term engine reliability. Finally, give particular attention to the suspension and braking systems, which can develop wear independent of mileage. Check the condition of the front and rear suspension bushes, control arm joints, and coil springs for any looseness, creaking, or uneven ride height, and listen for clunking noises when the car is driven over bumps. Inspect the brake discs for surface rust, scoring, or excessive thickness variation, and ensure the calipers move freely without binding or leaking fluid. A thorough visual check of the exhaust system for corrosion or cracks, and a quick assessment of fluid levels and colour (engine oil, brake fluid, and coolant) will round out a comprehensive pre‑purchase evaluation for this 2017 BMW 420.
