2021 MINI Cooper 1.5L Petrol · MM21 FFO

The most recent MOT, carried out on 6 October 2025, was passed but recorded two advisories – the front brake disc was noted as worn, though not yet beyond the legal limit, and the nearside front windscreen wiper blade was defective. Compared with the preceding twelve months this represents an improvement: the vehicle failed a dangerous test in June 2024 due to an off‑side front tyre bulge, but subsequently passed without any dangerous failures and only minor advisories have been noted. The overall maintenance trend therefore appears to be stabilising, with no repeat dangerous defects, though the presence of wear‑related advisories suggests that consumables are approaching the end of their service life. At 34,917 miles on a 2021 model the car averages just under 7,000 miles per year, which is well within the typical UK usage pattern for a small hatchback. The mileage does not indicate any periods of high‑intensity use, but the relatively low annual figure could also imply that the vehicle has spent extended periods stationary, a factor that can encourage corrosion of brake components, tyre sidewall ageing and battery sulphation. There are no obvious gaps in the recorded MOT dates, and the mileage progression appears consistent with normal wear rates for the drivetrain and suspension. Prospective buyers should give particular attention to the front brake assembly. Verify the disc thickness with a micrometre or have a workshop measure it; discs that are close to the minimum legal limit often produce a faint squeal or a pulsating feel under heavy braking. Inspect the brake pads for uneven wear and ensure the caliper pistons move freely without binding. The defective wiper blade should be replaced, and the windscreen examined for any cracks or chips that could propagate, especially around the stone‑chip advisory area. A thorough visual and tactile inspection of all tyres is essential – look for any bulges, sidewall cracks, or uneven tread wear that might indicate the previous off‑side tyre issue has recurred, and confirm that the tread depth exceeds 1.6 mm across the tyre width. Given the car’s age of five years, regardless of mileage, a comprehensive time‑based check is advisable. Examine the tyre sidewalls for age‑related cracking, as rubber can deteriorate after three years even on low‑mileage tyres. Test the 12‑volt battery voltage and, if possible, have its cranking amps measured, since prolonged storage can reduce capacity. Inspect the suspension bushes and coil springs for any signs of corrosion, leakage or excessive play, and listen for clunks when applying gentle pressure over bumps. Verify that the service book shows regular oil, filter and coolant changes, and consider a fresh change of engine oil, brake fluid and coolant if the last recorded service exceeds 12 months, as fluid degradation can affect performance and longevity.
