MINI ONE CONVERTIBLE2006 · 1.6L PETROL

This MINI ONE Convertible's most recent MOT, conducted on 7 February 2026 at 93,375 miles, passed, yet the maintenance trend is not reassuring. The tester flagged corrosion on three separate brake pipes, each obscured by grease or other material, a recurring advisory that first appeared in the August 2023 test at 87,675 miles and was present again at the same mileage during the failed test on the same date. The persistence of corroded brake pipework across consecutive tests indicates a worsening pattern of underbody deterioration rather than a resolving one. Suspension and subframe corrosion, noted as far back as August 2022 at 82,183 miles, further corroborates long-term exposure to moisture and a lack of proactive rust treatment. The vehicle's mileage profile is unusually low for a 2006 model, averaging roughly 4,669 miles per year. Between August 2023 and February 2026, a span of two and a half years, the odometer advanced just 5,700 miles. Such low annual use often means prolonged stationary periods, which accelerate rubber perishment, brake seizure, and localised corrosion of brake lines and subframes. The sparse mileage accumulation between 2022 and 2023, where the car covered only 5,492 miles in twelve months, reinforces the picture of intermittent use rather than regular, conditioning driving. A buyer should prioritise a thorough underbody inspection, focusing on the condition of all brake pipework, particularly the nearside and offside front and nearside rear lines where corrosion has been repeatedly documented. Suspension arm bushes and subframe mounting points demand close scrutiny, as worn bushes and surface corrosion were flagged as early as 2022 and have likely deteriorated further. The persistent oil leak, dismissed as not excessive in 2022 and again in 2023, warrants investigation for gasket or seal degradation that may have worsened with infrequent use. Front brake pads were noted as wearing thin in 2023, and with minimal mileage since, caliper binding or uneven pad wear remains a plausible concern. Tyre condition, particularly edge wear on the front axle, should be checked alongside the TPMS system, which has remained illuminated since at least 2023.
