2015 BMW 420 2.0L Petrol · YJ15 WHM

The 2015 BMW 420 holds a valid MOT certificate issued on 16 June 2025 at 65,524 miles, following a failure on the same day for a low nearside headlamp aim and play in the offside steering rack inner joint. The immediate retest passed with the steering rack play and both front brake discs still flagged as worn, pitted or scored but not seriously weakened. This pattern reveals a maintenance trend that is stable but permissive. The tester has repeatedly noted the same front brake disc wear and steering rack play across multiple tests without them escalating to serious failure, suggesting the owner tolerates minor wear rather than proactively rectifying it. The vehicle is roadworthy today, but the record shows a pattern of deferring minor mechanical wear rather than resolving it. The mileage progression tells a clear story of very light use. In June 2023 the odometer read 47,011 miles. By June 2024 it had reached 57,480 miles, a jump of 10,469 miles in one year. The following year, from June 2024 to June 2025, the car covered just 8,044 miles. That is roughly 5,957 miles per year on average over the vehicle's life, well below the UK average. The sharp increase between 2023 and 2024 followed by a drop in annual mileage suggests a change in ownership or usage pattern around mid-2023. The MOT record is consistent and well-documented with no gaps, giving confidence that the mileage is genuine. A buyer should focus on the front suspension and steering components. Play in the offside steering rack inner joint has appeared in every test from June 2024 through June 2025, indicating a persistent wear point that has not worsened to a fail but has not been repaired. The front brake discs were flagged as worn, pitted or scored in both 2024 and 2025, meaning they have been operating in a degraded condition for at least a year. Inspect the inner tie rod ends, rack gaiter for splits, and check whether the discs have developed lipping or hot-spotting beyond what the tester considered acceptable. The nearside front headlamp aim was too low in the June 2025 failure, so verify the headlamp levelling system and that the beam pattern is even and correctly aimed. Tyre condition has been a recurring theme. In June 2024 the offside front tyre was at 1.8mm with a bald inner edge and the nearside front had a structural bulge, indicating the previous owner ran mismatched or neglected rubber. All four tyres showed edge wear consistent with underinflation or worn suspension bushes. Check the inner sidewalls for sidewall damage, confirm the tyre sizes match across each axle, and inspect the front suspension bushes and dampers for play. The low annual mileage means the car may have spent long periods stationary, so look for flat-spotted tyres, perished rubber bushes, and any signs of corrosion on brake lines or subframe mounting points that static storage can accelerate.
