Peugeot 108 I phase 2 (PA/PB) (2018 – 2021)

Reliability score : 9.2/10

The Peugeot 108 Phase 2 (2018–2021) represents the mature and most reliable iteration of the French city car. Co-developed with Toyota (Aygo) and Citroën (C1) and built at the TPCA plant in the Czech Republic, it heavily benefits from Japanese engineering. The 2018 facelift brought minor aesthetic tweaks, improved sound insulation, an updated infotainment system (compatible with Apple CarPlay and Android Auto), and crucial mechanical updates to meet Euro 6.d-temp emissions standards. The most significant change for reliability was the discontinuation of the PSA-sourced 1.2 PureTech engine, leaving the bulletproof Toyota-sourced 1.0-liter engine (upgraded to 72 hp) as the sole powertrain for the vast majority of this phase. This makes the Phase 2 Peugeot 108 one of the most dependable used

✅ Strengths

Exceptional mechanical reliability (thanks to the Toyota 1.0 engine)
Very low running costs (fuel, insurance, and maintenance)
Compact dimensions and tight turning circle, perfect for the city
Upgraded infotainment in Phase 2 (Apple CarPlay / Android Auto)
Timing chain on the 1.0 engine (no expensive belt replacements)

⚠️ Weaknesses

Small boot capacity (196 liters)
Limited sound insulation at highway speeds
Firm ride quality on rough city streets
Cramped rear seats with pop-out only windows
The rare 1.2 PureTech versions carry significant engine failure risks

🎯 Verdict

The Peugeot 108 Phase 2 is an outstanding choice for a used city car, provided you stick to the 1.0 VTi 72 engine. Because it is essentially a Toyota Aygo underneath, it offers Japanese reliability wrapped in French styling. It is cheap to run, easy to park, and the Phase 2 updates bring the technology up to modern standards. Avoid the 1.2 PureTech engine entirely due to its well-documented timing belt issues. If you find a well-maintained 1.0 VTi, you can buy it with absolute confidence.
