2025 Lexus Gx550 Summary

The new Lexus GX 550 showcases a brand new design for its third-generation iteration but the model is new to the Australian market.

And while it hasn't been as hotly anticipated as its cousin, the Toyota Prado, it's still one that should excite. It's a capable full-time four-wheel drive that manages to look good on- and off-road! It feels like a breath of fresh air.

Will it find itself more likely adorning the garage of a city slicker? Perhaps, but you can't deny it has some star power now with its design and it couldn't have come soon enough. Especially when you compare the flagship Sports Luxury grade my family and I have on test to its European luxury rivals, the BMW X7 and Land Rover Defender.

2018 Mercedes-Benz S600 Summary

Imagine a car that can pretty much drive itself, if you let it. And it’ll do that while you get a massage, pump some Beyonce, and enjoy the fragrance of a field full of flowers… And then, it can teach you to do stretches and exercises in the driver’s seat.

It may sound like fictional fiction, but it’s factual fact. And it’s the Mercedes-Benz S-Class 2018 model, which has taken the so-called ‘wellbeing’ of the driver to a new level.

The facelifted model has seen plenty of styling changes and some tech upgrades, and while making the flagship car in a particular brand’s line-up is often a task fraught with issues, the German company’s big, expensive, luxurious, limousine is undoubtedly a more thoughtful car for 2018.

But just remember, its predecessor was considered - at least for a little while - as the best car in the world by some automotive journalists. 

Now Mercedes-Benz has updated it, and it reckons it’s better than before, bringing a bunch of new technology, new engines, a reworked model range and, perhaps not essentially, but still pleasantly, lower pricing.

Read on to see how Beyonce factors into the equation.
