2016 Smart Forfour 1.0L Petrol · EY66 BZN

The 2016 Smart Forfour presents a mixed maintenance picture. The most recent test on 14 November 2025 at 52,532 miles resulted in a pass, yet the tester flagged front brake discs worn, pitted or scored, but not seriously weakened. This advisory carried over from the failed test on 31 October 2025 at 52,480 miles, where both rear tyres also required attention. The fact that the front brake disc advisory persisted across two tests within two weeks suggests the discs were not replaced between inspections. The maintenance trend is neither clearly improving nor worsening. It reflects a pattern of addressing only the minimum to pass, with recurring brake and tyre wear issues left to accumulate rather than resolved proactively. The mileage profile is notably low for a ten-year-old vehicle. At 52,532 miles, the annual average sits at roughly 5,253 miles per year. The record shows a jump of 5,958 miles between November 2023 at 41,574 miles and November 2024 at 47,558 miles, followed by a further 4,974 miles to the November 2025 test at 52,532 miles. This indicates a recent uptick in usage after what appears to have been a period of lighter use or possible standing earlier in the vehicle's life. The MOT history itself is sparse, with only five tests recorded across four years, leaving gaps in oversight that make it harder to establish a complete wear and service timeline. A buyer should pay close attention to the front brake discs, which have been flagged consecutively. Pitting and scoring beyond surface wear can compromise braking efficiency and accelerate pad degradation. The rear shock absorbers also warrant inspection. In the November 2023 test at 41,574 miles, both rear units were noted as having a light misting of oil, an advisory that was not repeated in subsequent tests. This could mean the issue was addressed, or it may simply have not reached the threshold for a fail. Either way, a physical check for oil seepage, damping performance, and bounce test behaviour is advisable. Tyre condition has been a recurring theme. Between the October 2025 failure and the November 2024 pass, rear tyres repeatedly appeared on the verge of the legal tread limit or showed edge wear and sidewall damage. This pattern suggests either alignment or suspension geometry issues, or simply that previous owners ran tyres down to the minimum rather than replacing them early. A buyer should inspect all four tyres for uneven wear patterns, check the sidewalls for cracking or perishing, and consider having the wheel alignment and suspension bushes examined. The low annual mileage makes structural corrosion less likely, but a thorough underbody check for rust on subframes, brake lines, and exhaust mounting points remains prudent.
