2016 BMW 420 2.0L Diesel · A23 JAM

The 2016 BMW 420 presents as roadworthy with a stable maintenance trend. The most recent test on 21 October 2025 at 110,134 miles returned a pass with no defects recorded, continuing an unbroken run of clean results across the previous four years. Annual mileage sits at roughly 11,000 miles, typical for a ten-year-old vehicle. The records show steady accumulation: 55,908 miles in February 2022, 62,310 in January 2023, 81,342 in February 2024, 99,150 in February 2025, and 110,134 by October 2025. No gaps or sudden spikes appear. The DVSA data is sparse on advisories, with every entry listing zero defects, which suggests either disciplined upkeep or tests conducted on a car with no wear items near failure thresholds. A buyer should still commission an independent inspection of suspension bushes, coil springs, and brake disc thickness, as the MOT record offers no visibility of components wearing within tolerance. The absence of corrosion or structural advisories is reassuring, but Nissan-era testers often miss early subframe rust on rear-drive BMW platforms until it breaches the 40mm perforation limit. Given the clean history, previous owners likely serviced the car to a reasonable standard. Verify full service paperwork and check for genuine BMW parts on the timing chain and turbo oil feed, since high-mileage N20 engines suffer premature chain stretch not captured by MOT tests.
