Used MG MG3 for sale

All MG3s come equipped with front, side and curtain airbags, stability control and ISOFIX mounting points as standard. Facelifted models offer additional features such as rear parking sensors and, on top trims, a reversing camera. It’s worth noting that the MG3 missed out on some advanced driver aids found in newer rivals.

The MG3 is powered by a single 1.5-litre petrol engine delivering 105-106hp and paired with a five-speed manual gearbox. There’s no automatic option. Pre- and post-facelift models share essentially the same engine, though efficiency improved slightly from 2016 onwards and mild performance tweaks were made.

Earlier (pre-2018) MG3s offer a basic radio with small buttons, Bluetooth and DAB (on most trims). The 2018 facelift introduced an 8-inch colour touchscreen with Apple CarPlay on mid-range and above, rear parking sensors and, in top models, a reversing camera and upgraded speakers. Android Auto is not supported.

Depending on the model year, official MPG figures range from 47 to 51mpg. Facelifted, WLTP-rated versions claim 47.1mpg combined. Earlier models may manage closer to 48–51mpg, though real-world performance can be lower, especially if driven briskly. CO2 emissions range from 124 to 140g/km.

Check for signs of interior wear, especially on the plastics, and make sure door seals are dry as some early models had issues with water ingress. On older MG3s, the timing chain should have been replaced or upgraded. Also, test parking sensors and clutch function, as both have known faults. For peace of mind, consider an inspection via The AA Vehicle Inspection.

Owners report strong mechanical reliability, with only isolated cases of major faults. Minor electrical gremlins can crop up – mainly sensors or dashboard issues – but dealer service is generally well regarded. MG3s are cheap to run and solidly built for the price, though MG’s brand reliability ranked below average in recent surveys.
