Used MG 3 2013-2024 review

The small car class seems to be getting more and more expensive by the hour, but the MG 3 has been trying to buck that trend even since it arrived in 2013.

It was positioned as a good-value alternative to rivals such as the Dacia Sandero, Kia Rio and Vauxhall Corsa when new. It remains affordable when used, too, but more on that on the next page...

Engines & Performance: A 1.5-litre petrol is the only engine on offer, and while it offers a great headline power figure for the class (105bhp), this non-turbocharged unit isn’t as flexible as more modern offerings.

You really have to thrash it in order to make progress. When you do so, the unit sounds a bit rough, plus it rumbles away in the background on the motorway, unlike more hushed engines you can find inside rivals – the VW Polo, for example.

Ride & Handling: You’ll also notice that the 3's ride is on the firm side. This is great for handling, where the 3 feels rather sharp fleet and decent fun. However, the downside is the ride is abrupt with potholes, is unsettled over rough roads and transmits plenty of road noise into the interior.

The steering is heavy for a small car, too, making parking a bit trickier. It is accurate, though, enabling you to place the car through corners with ease.

Interior & Practicality: The 3 is spacious inside, with plenty of head room. You can fit two tallish adults in the rear seats, thanks to a surprising amount of leg room. The steering wheel adjusts only for height, though, so the driving position isn’t as comfortable as it could be.

The quality of plastics inside isn’t great, but considering how cheap the 3 was when new, this is to be expected. What does really date the interior is that there isn't an infotainment screen on models made before the 3 was given a facelift in late 2018, with a very fiddly radio unit that has lots of small buttons. Post-facelift 3s have a much more up-to-date 8.0in touchscreen that's responsive and has an attractive layout. It only has Apple CarPlay smartphone connectivity, though, not Android Auto as well.

Trims & Equipment: Speaking of pre and post-facelift 3s, there's a marked difference between the two in terms of standard equipment. Entry-level 3Time models are best avoided in favour of mid-range 3Form and 3Form Sport, because you get air conditioning, a DAB radio, Bluetooth and a leather-wrapped steering wheel, with 16in alloy wheels and some exterior styling tweaks exclusive to the 3Form Sport. Additional luxuries were reserved for the range-topping 3Style, which had diamond-cut wheels, cruise control, automatic lights and wipers and rear parking sensors. The 3Style Lux came with leather seats.

The facelift led to a rationalisation of the MG 3 range to just three models: Explore, Excite and Exclusive. Explore is a bit basic, with only 14in steel wheels, Bluetooth and central locking, so look instead for an Excite version with an 8.0in colour touchscreen, rear parking sensors, air-con and 16in alloys. Top-spec Exclusive models come with a reversing camera, cruise control, an upgraded stereo and sports seats.

MPG: If you go for a pre-2016 model, official NEDC fuel economy is 48.7mpg and CO2 emissions are 136g/km. Examples produced after 2016 improve upon those figures, reducing consumption to 51.4mpg and CO2 to 124g/km. However, facelifted versions are rated under the current (and slightly more realistic) WLTP system and therefore have slightly worse figures of 47.1mpg and 140g/km.

Road tax: Early examples of the 3 registered before 1 April 2017 will be charged road tax based upon the amount of CO2 they produced, whereas ones registered after this date incur a flat rate fee regardless of the emissions produced. This is currently £190 per year.

Insurance and servicing: The MG 3 sits in a low insurance group, helping to keep running costs down. However, both fuel and yearly road tax are high compared with rivals, because the 3 has a relatively large petrol engine.

Servicing is usually every 15,000 miles, but if your car is fitted with the start-stop function (a fuel-saving feature that cuts the engine when the car is stationary), it'll need to be seen every 10,000 miles.

Reliability

The MG 3 proves itself mechanically sound, according to our 2023 What Car? Reliability Survey, with only a few major repairs noted among the models from recent years. Minor electrical glitches like sensor faults and dashboard display issues were reported, but these were not widespread.

Dealer service for the MG 3 generally received high marks for efficiency and helpfulness, with many owners satisfied with the prompt and proactive problem resolution. However, some owners expressed concerns over the occasional lack of replacement part availability, leading to extended repair times.

Since there's only one engine and gearbox choice, this bit is quite simple.

The 3Style seems to be one of the more common trims available and has all the equipment we like from the 3Form and 3Form Sport with a few added luxuries for not much more money.

If you happen to be going for a facelifted model from 2019 onwards, there isn't much of a price difference between mid-range Excite and top-of-the-range Exclusive, so you might want to stretch to the higher-spec car for more equipment.

Our favourite MG 3: 1.5 3Style

The Dacia Sandero is a very roomy car and can have it with a more modern, turbocharged engine. It's similarly priced when used, too.

Value for money has always been a key selling point of the Kia Rio, and most examples will still have some warranty coverage left. The Rio's interior is well put together, if a little dull, and the car gets plenty of standard equipment.

Then there’s the Vauxhall Corsa, which has been a big seller for many years now thanks to low prices, affordable running costs and cheap insurance rates. It’s not the most exciting small car to drive, but it is one of the more spacious cars in its class.
