2026 Mercedes-Benz Gls450 Summary

The ‘Upper Large SUV over $120K’ segment of the Aussie new-car market is what you might call the top end of town, not only in terms of the extravagant models available but also their purchase prices, which stretch well into six figures and require monthly lease payments that rival home mortgages.

It’s where you’ll find some of the most prestigious marques in the automotive world including Rolls-Royce, Aston Martin, Bentley, Ferrari, Lamborghini, Range Rover, Lexus and BMW. And, of course, Mercedes-Benz with its big GLS which represents the flagship of the German manufacturer’s SUV fleet.

It was given a refresh in 2023 with cosmetic and multimedia upgrades along with powertrain enhancements, but there have only been minor changes since then. We were recently entrusted with the keys to the latest GLS to see if the ‘S-Class of SUVs’ leaves any room for improvement.

2024 Suzuki Swift Summary

Few cars have had the sheer staying power of the Suzuki Swift.

Except for a four-year hiatus as the original Ignis from 2001, the Japanese supermini has been a segment mainstay since 1983, winning over consumers worldwide as an inexpensive, economical and reliable yet fun option in the Toyota Yaris class.

In Australia, its impact has been even more profound, providing Holden with its famous “beep-beep” Barina for two early iterations from 1985, while also introducing us to the pocket rocket decades before the Volkswagen Polo GTI, with the Swift GTi of 1986.

Now there’s this – the sixth-gen model in 41 years if you exclude that Ignis – doing what the little Suzuki has always done: offering buyers a great budget alternative. But this time, in this new-electrification era, where precious few attainable choices remain.

Is it any good? Let’s dive straight in.
