The Chinese owned car manufacturer has finally broadened its range with the MG Motor UK MG3 supermini. With prices starting from £8,399, the new car is not the cheapest in the sector, but decent levels of standard equipment puts it nose to nose with equivalent Dacia Sanderos and Chevrolet Sparks.

Running costs

One of the highlights of MG3 running costs is the car’s insurance group rating. It’s classified in Group 4E, which is very low indeed.

The 1.5-litre petrol engine averages a claimed 48mpg, although how close you’ll get to this figure in the real world given the need to sometimes work the car fairly hard to stay with traffic is debatable.

As for road tax, carbon dioxide emissions of 136g/km place the car in an uncomfortably high VED band for its size.

That’s offset by an attractively low purchase price across the range.

Future residual value forecasts suggest that after three years and 60,000 miles the MG3 will retain approximately 34 to 35 percent of its value, depending on spec.

MG is offering eight different PCP finance schemes from launch.

Bear in mind that the MG dealer network is relatively small and so you may have to travel some distance to get the car serviced.
