MG MG3 I (SB) (2013 – 2018)

Reliability score : 6.8/10

The MG3 (internal generation SB/SW under the SAIC Motor era) marked the true return of the octagonal brand to the European market (mainly in the United Kingdom) in the highly competitive B-segment hatchback category. Largely designed at the Longbridge technical center in the UK but manufactured in China, it positions itself as a 'low-cost' alternative with a sporty look. Positioning: It directly competes with the Dacia Sandero on price, while offering more dynamic road handling, similar to an older generation Suzuki Swift or Ford Fiesta. Evolutions: Launched in late 2013 in Europe, it received a slight technical update in 2015 (transition to Euro 6 standard with the addition of Stop & Start) before undergoing a major facelift in late 2018 (outside the scope of this report). Overall design

✅ Strengths

Extremely low used purchase price (significant depreciation)
Generous interior space for the B-segment (rear legroom)
Dynamic road handling (well-tuned chassis, communicative hydraulic steering)
Basic mechanical reliability (old-school naturally aspirated engine, few complex parts)
Very low insurance cost (ideal for young drivers in the UK)

⚠️ Weaknesses

1.5L engine lacking low-end torque (requires high revs) and very fuel-thirsty
Very basic interior plastic quality (prone to scratches and rattles)
Poor sound insulation (wind and road noise on the highway)
Outdated passive safety (3 Euro NCAP stars, lack of modern driving aids)
Limited dealer network (depending on European countries) complicating maintenance

🎯 Verdict

The first-generation MG3 (SAIC) is a rational purchase only if budget is the number one criterion. Its 1.5 VTi-TECH engine, although anemic and thirsty, has the merit of being robust thanks to its rustic design. It offers surprising interior space and an enjoyable chassis. However, the mediocre finish quality, non-existent sound insulation, and outdated safety make it a difficult car to recommend compared to a used Dacia Sandero or Suzuki Swift, unless found at an unbeatable price. Buying advice: Prioritize a post-2015 model (Euro 6 with Stop & Start) with a full service history. Avoid examples showing corrosion under the chassis or an excessively juddering clutch.
