The MG3 Generation I (SB) (often referred to as Mk1 in the UK, though technically the second generation globally following the SW) marked MG's serious return to the mainstream supermini segment under SAIC Motor ownership. Launched in the UK in 2013, it was positioned as a budget-friendly, spacious, and highly customizable hatchback aimed at young drivers. While it earned praise for its surprisingly sharp chassis and engaging handling (tuned in the UK), it was heavily criticized for its aging, naturally aspirated engine, high CO2 emissions, stiff ride, and cheap interior plastics. A minor facelift in 2016 brought a cleaner Euro 6 engine and stop-start technology, before a major overhaul in 2018.
The MG3 (2013-2018) is a mixed bag. It offers genuine fun on a twisty road, plenty of interior space, and low insurance costs, making it an appealing first car. However, the 1.5L engine feels dated, lacks low-end torque, and is relatively thirsty. Reliability is strictly average, with timing chains, clutch wear, and electrical gremlins being the main concerns. It makes sense only as a very cheap, low-mileage used buy. A flawless service history is absolutely mandatory to avoid timing chain bills.
