What to check before buying a 2021 Polestar 2 Ev Fwd
The failure pattern for this year is specific enough to inspect against: tyres accounted for 8.3% of tests. Start there.
- Tyres (8.3% 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.
- Seat belts & restraints (1.0% of tests): Belt damage or faulty pretensioners — usually straightforward but safety-critical. Typical repair: £50–£300.
- Visibility (0.9% of tests): Wipers, washers, mirrors and screen damage — usually inexpensive, but check for chips in the driver's line of sight. Typical repair: £15–£150.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
