MG MG3 I (SB) (2013 – 2018)

Reliability score : 6.8/10

The first-generation MG3 under the SAIC Motor era (often referred to as Mk2 in the UK or Gen 2 globally, with the SB code corresponding to this iteration) marked the return of the MG brand to the B-segment (versatile city cars) in Europe. Initially launched in China in 2011, it arrived on the British market in 2013 with specific chassis tuning. Positioned as an affordable alternative to the Dacia Sandero, Skoda Fabia, or Ford Fiesta, it stands out with generous interior space, dynamic road handling, and numerous customization options. However, it suffers from a 'low-cost' design evident in its basic interior plastics, imperfect sound insulation, and an aging, fuel-thirsty naturally aspirated engine. A major facelift (Phase 2) occurred in 2018, profoundly changing the front end and interior

✅ Strengths

Very attractive used purchase price (significant depreciation)
Dynamic road handling and precise steering (UK chassis tuning)
Generous rear passenger space for the B-segment
Very low insurance cost (ideal for young drivers in the UK)
Simple naturally aspirated engine (no turbo, no DPF, no dual-mass flywheel)

⚠️ Weaknesses

1.5 engine lacking torque at low revs, requiring high revs
High fuel consumption for the category (often > 6.5 L/100km)
Interior plastic quality (hard, prone to scratches and rattles)
Poor sound insulation on the highway (wind and road noise)
Limited dealer network and parts availability outside the UK

🎯 Verdict

The MG3 (2013-2018) is a sensible purchase for tight budgets. It offers the space and road handling of a modern European city car for the price of a much older used car. However, its 1.5 naturally aspirated engine is from another era: it lacks flexibility and consumes too much fuel. Mechanical reliability is generally good thanks to its simplicity, but it requires rigorous maintenance (annual oil changes) to avoid timing chain problems. Peripherals (thermostat, clutch) are its main weaknesses. To be bought with a complete service history and after a thorough inspection of the cooling system.
