What to check before buying a 2020 500 Pop Mhev
Before buying a 2020 Fiat 500 Pop Mhev, focus on the areas it most often fails on. Tyres accounted for 8.4% of tests for this year.
- Tyres (8.4% 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.
- Lighting & signalling (3.6% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Visibility (3.4% 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.
