2020 MG 3 Summary

This story has been updated in February 2022 to reflect market changes and pricing adjustments for the MG3. It was originally published in the first half of 2020.

My time at CarsGuide started in October 2017, and since then I’ve booked literally thousands of cars across Australia. One car that has eluded me - and the CarsGuide team - over that period is the one you see here: the MG3. Or the MG MG3, or MG 3, if you wish.

Despite asking MG’s Australian arm countless times to loan an MG3 hatchback over that period, the company in charge of the brand’s PR in Australia refused to agree to loan us a vehicle to test. Now the company has an in-house PR team with a pretty decent fleet of press cars, yet still, no MG3.

Over the years, our desire to review the MG3 hatch - and to help you decide whether it's right for you or not - has only gotten stronger because sales have skyrocketed. Back in late 2017 the brand was averaging only a handful of cars per month - indeed, just 52 examples of the MG3 were sold in total in 2017.

Since then, the MG3 has skyrocketed, and it is the best-selling light car in Australia. In 2021, the brand moved more than 13,000 MG3s - meaning it is averaging 250 cars sold per week. Makes the paltry 2017 numbers look a bit meagre. In becoming the number-one seller in the segment, it has beaten big-name rivals including the Kia Rio, Mazda 2 and now defunct Honda Jazz, while also being well clear of the cheaper Kia Picanto, which is what many people will be shopping this car against if price is a key driver for their decision.

And that's the case in point, really - a lot of its success comes down to the price of the Chinese-built, British-badged city car. It’s cheap - but is it a cheerful experience? We got the chance to find out in 2020, thanks to a friendly MG dealership in NSW - and this review has been updated with the most current pricing, because nothing else has changed.

2024 Mazda 3 Summary

Half a decade on, the current-generation Mazda 3 has weathered a world of change.

Cheap cars have vanished. Electric vehicles are commonplace and the small car class it belongs to has been decimated by SUVs. Big names like the Ford Focus, Holden Astra and Mitsubishi Lancer are history.

But while it looks identical to the car unveiled at the 2018 LA Auto Show, today’s Mazda 3 has also evolved, albeit gently.

Let’s see how competitive the latest and improved (as well as more expensive) version is.
