2017 MINI ONE 1.2L Petrol · ET17 AAZ

The 1.2-litre petrol MINI ONE delivers reasonable fuel economy, typically in the mid-40s to low-50s mpg for mixed driving, which suits the low-mileage usage pattern suggested by this vehicle's history. Road tax for a 2017 petrol MINI falls in a relatively modest band, though post-2017 vehicles meeting Euro 6 standards generally attract a flat £190 standard rate for cars priced above £40,000 new — the standard MINI ONE did not, so it should sit at the lower annual VED rate. Insurance is typically in group 12-15 for the ONE variant, keeping premiums manageable. The biggest running cost concern here is tyres — the MOT history shows three consecutive advisories for tyre condition, suggesting the vehicle may need a full set within the next 6-12 months, costing roughly £300-£450 fitted. Estimated annual running cost: £1,200-£1,500 including fuel, tax, insurance, and maintenance given the tyre wear pattern observed.

Start with a close inspection of all four tyres — the history shows nearside front tyres repeatedly flagged for low tread (3-4mm) and uneven edge wear, alongside rear tyre cracking. Uneven edge wear on a low-mileage car often points to alignment issues, suspension wear, or prolonged under-inflation, all of which warrant investigation on a ramp. The recurring bonnet stiffness advisory spanning three MOTs is unusual; check that the bonnet catch and hinges operate smoothly and that the stiffness has been resolved rather than simply ignored. The TPMS fault that caused the June 2026 failure needs verification — confirm whether a new sensor was fitted or whether the system simply required reinitialisation after a tyre change. Examine the nearside front and rear bodywork flagged in 2024 for quality of repair, panel gaps, and evidence of corrosion creeping through any respray. Finally, given the very low usage, check the battery state of health, inspect brake discs for surface corrosion (a common issue on garaged low-mileage cars), and verify the coolant and oil have been changed within their recommended intervals despite the low odometer reading.
