2016 BMW 420 2.0L Petrol · KM66 GPJ

The 2016 BMW 420 holds a current MOT valid until late May 2026, having passed its most recent test on 29 May 2025 at 106,999 miles. The maintenance trend is broadly stable, though the record reveals a pattern of minor recurring advisories rather than escalating mechanical failure. The vehicle has not suffered a test failure since June 2024, and the most recent pass was clean aside from a nearside front tyre worn to 2 mm and a child seat obstructing the inspection of the nearside rear adult belt. No corrosion, emissions, or structural integrity concerns have been flagged in any recorded test. The mileage progression tells a clear story of changing use. Between June 2022 and June 2023, the car covered roughly 21,700 miles, then accelerated sharply to approximately 25,300 miles in the following twelve months. The most striking jump occurred between June 2024 and May 2025, when the odometer moved from 84,813 to 106,999 miles, an increase of over 22,000 miles in under a year. That spike suggests sustained high-speed motorway use, which typically favours engine and gearbox longevity but places greater demand on brakes, tyres, and suspension bushes. The current total of 106,999 miles sits at roughly 10,700 miles per year over the car's ten-year life, which is typical for its age. Buyers should pay close attention to the front axle. The tester flagged front brake discs as worn, pitted, or scored in June 2022, and front brake pads were noted as wearing thin at the same test. With over 69,000 miles covered since that inspection, those components are well past due for replacement unless receipts confirm renewal. The offside rear shock absorber was recorded with a light oil misting in 2022, a condition that commonly worsens over time and should be checked for damping performance and leaks. Tyre condition has been a recurring advisory across multiple tests, with both nearside and offside front tyres repeatedly worn to or below legal limits, suggesting possible alignment or suspension geometry issues that are causing uneven edge wear. The June 2024 failure for non-conforming front and rear registration plates is a minor administrative matter, but it does hint at a lack of attention to detail. Combined with the repeated child seat obstructions preventing full seatbelt inspections, a thorough interior and mechanical inspection is advisable. Focus on suspension bushes, coil springs, and exhaust emissions during any pre-purchase check, as these components are not explicitly covered in the MOT advisories but are common failure points on high-mileage BMWs of this generation.
