2024 MG MG3 Summary

A number of established small cars are becoming more expensive and less popular. The Toyota Yaris, Mazda2 and Suzuki Swift were once the go-to first car, but now start at around $25,000.

This repositioning was great for MG and its sub-$20,000 MG3, which has spent much of the last few years as Australia's most popular light car. It’s hard to deny a low price will open many wallets.

But now in its new generation, the MG3 is thousands of dollars more expensive than before, starting in the mid-$20K range and headed even further up with a new hybrid drivetrain option. We jump in the base petrol Excite to find out if the value is still there for this British-branded, Chinese-built hatchback.

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.
