What to check before buying a 2020 Polestar 2 Pilot Ev
Before buying a 2020 Polestar Polestar 2 Pilot Ev, focus on the areas it most often fails on. Tyres accounted for 7.1% of tests for this year.
- Tyres (7.1% of tests): Usually a quick, known-cost fix, but check tread, age and uneven wear (which can hint at alignment or suspension issues). Typical repair: £50–£120 per tyre.
- Body, structure & corrosion (3.5% of tests): The one to take seriously on older cars — corrosion to structural areas can be costly and is an MOT failure. Typical repair: £200–£1,500+.
- Lighting & signalling (2.9% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
