MG ZS I (essence) (2017 – 2021)

Reliability score : 7.8/10

The first-generation MG ZS (before its major facelift in late 2021) marks the pragmatic return of the British brand under the aegis of the Chinese giant SAIC Motor. Positioned at the border between urban SUVs (B-SUV) and compact SUVs (C-SUV), it established itself thanks to an unbeatable price/space/equipment ratio, directly competing with the Dacia Duster. While the 100% electric version (ZS EV) boosted sales in Europe from 2019, the internal combustion (petrol) versions form the core of the offering in many global markets. The petrol ZS shines with its mechanical simplicity but suffers from imperfect sound insulation, basic interior plastics, and a slow infotainment system. It's a sensible purchase, ideal for tight budgets looking for a family vehicle with a long warranty (5 to 7 years d

✅ Strengths

⚠️ Weaknesses

🎯 Verdict

The first-generation MG ZS is an eminently rational choice. If you're looking for automotive thrills or premium finishes, look elsewhere. However, for a robust, spacious, and economical family mover, it excels. The 1.5 VTi engine is to be preferred for its bulletproof reliability, provided you accept its laborious acceleration. The 1.0 T-GDI offers a better compromise for road use. Buying used is highly recommended, as the significant depreciation in the early years works in the buyer's favor, often while still benefiting from the remainder of the manufacturer's warranty. Negotiate firmly if the service history is not 100% clear or if the electronics show signs of weakness.
