2013 Ford Focus 1.6L Diesel · NV13 AAO

A thirteen-year-old Ford Focus presenting 104,261 miles carries a clearly defined corrosion narrative that any prospective buyer must take seriously. Across every recorded MOT since 2022, the vehicle has surfaced advisories for subframe corrosion at both the front and rear mounting prescribed areas, corroded front and rear suspension arms, corroded rear coil springs, surface rust across suspension and chassis components, and light oil misting on the rear shock absorbers. The most recent test on 14 November 2025 returned a Pass but reinforced this pattern, flagging both rear coil springs as corroded, the offside front lower suspension arm pin or bush as worn, and the rear subframe as corroded without significant loss of structural rigidity. One failure is on file from 7 December 2022, recorded for a nearside front tyre below the legal 1.6 mm tread depth alongside advisories for subframe and suspension arm corrosion on both sides. The trend is not deteriorating in the sense of new failures, but the underlying advisories are persistent and recurring rather than transient, which indicates an ongoing corrosion process typical of a Focus of this generation exposed to winter road salt over many seasons. Annual mileage averages out at roughly 8,020 miles per year, which sits broadly in line with typical usage for a car of this age and means the recorded mileage gaps between tests are not suggestive of long periods off the road. The progression from 2022 through to late 2025 implies steady rather than sporadic use, so the wear observed in the test record reflects accumulated service rather than a vehicle left standing and then pressed back into duty. Mechanically, this kind of consistent annual mileage on a Focus of this age is consistent with the advisories shown: brake pads reaching the thin end of their service life by 2024, tyres approaching the legal tread limit on multiple occasions, and progressive corrosion setting into underbody components rather than isolated failures of a single part. Any test drive should concentrate on the suspension and underbody components specifically flagged in the MOT record. Listen for clonking or knocking from the front end over uneven surfaces and speed humps, paying particular attention to the offside front lower arm pin or bush noted as worn in the 2025 test, and feel for any vagueness or shimmy through the steering wheel that could point to further wear in those bushes. Listen at the rear for any change in ride quality over broken surfaces that might suggest the corroded rear coil springs are nearing the end of their functional life, and listen for any hiss or uneven damping behaviour from the rear shock absorbers, which were previously noted as lightly misting with oil. Inspect the rear and front subframes and suspension arms visually for advanced corrosion, flaking, or any visible distortion, and pay close attention to the tyre shoulders, since both nearside rear and offside front tyres have been recorded as worn close to the legal limit or on the edge, which can indicate misalignment, worn bushes, or simply ageing rubber compounding the chassis deterioration. The braking system warrants careful attention as well, particularly given that the 2024 test recorded front brake pads wearing thin on both sides and that the 2025 advisories did not specifically revisit brake condition. On the road, check for any pulling to one side under firm braking, a soft or spongy pedal, or any judder through the pedal that could indicate warped discs in addition to pad wear. Inspect all four tyres for both tread depth and even wear across the carcass, as the recurring edge wear advisories on the rears could reflect either geometry issues aggravated by tired suspension bushes or simply sustained urban use. Finally, examine the underside thoroughly with a torch and, ideally, on a ramp, focusing on the subframes, suspension arms, anti-roll bar, and rear coil springs for any corrosion that has progressed beyond the surface level described in the MOT advisories, since the recorded trend suggests these areas will continue to deteriorate and may soon move from advisory status to a defined structural defect on a future test.
