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.

2025 Rivian R1S Summary

An American all-electric car brand with a unique take on the automotive industry, an up and down share price and a cheaper model in its future plans. You could be mistaken for thinking I’m talking about Tesla, but I’m not.

Recently CarsGuide got the opportunity to experience an alternative electric car brand, and one that, despite having many similarities to Tesla, is also in many respects its polar opposite.

I’m talking about Rivian, which is very much behind Tesla in terms of sales, market cap and just about every other measure. But what it does have is a compelling line-up of electric vehicles, with plans for expansion, including an eventual entry into Australia.

Back in 2023 we drove the brand’s ute, the R1T, but on a recent trip to Los Angeles we sampled the brand’s other model, the R1S SUV. It was an eye-opener to see how far the brand has come in two years and showcased just how different Rivian is from Tesla.
