2020 Audi A6 Summary

The Subaru Outback has a lot to answer for. Way back in 1994 the Japanese brand created the high-riding wagon scene - and while the idea never really took off with most mainstream makers, European luxury brands seemingly loved the idea of a rugged estate. It’s another niche to fill, after all.

This led to the Volvo V70 Cross Country in 1997, and Audi followed suit with the A6-based Allroad quattro back in 1999. 

Other luxury brands have entered the fray since then, and obviously the market has proliferated with SUVs… but they’re not the same as a high-riding station wagon.

There has been evolution in the Audi Allroad line-up over time: in 2015 the company added the smaller A4 Allroad, while the original larger A6-based Allroad wagon continues to cop the rough-and-tumble treatment, as it has for decades now.

So, since the all-new Audi A6 Allroad has just arrived in Australia, we thought we’d see what it’s like. And perhaps more pertinently, maybe we’ll be able to answer the question that many of you probably have: Should you buy a high-riding wagon? Or is it smarter to just buy an SUV?

2022 Mercedes-Benz C300 Summary

Australia's relationship status with the Mercedes C-Class has long been… complicated.

Over 40 years and five generations, the German midsized luxury sedan has been a paragon of efficiency and safety on one hand, but on the other, well, the quality and ride comfort haven't lived up to brand expectations.

Now the completely redesigned version has landed in Australia, with shrunken S-Class limousine styling to take on not only the BMW 3 Series, Audi A4 and Genesis G70, but rivals as disparate as the Hyundai Ioniq 5 and Tesla Model 3.

The question is? Is this latest, sixth-generation, new-from-the-ground-up C-Class good enough to take on all those and more? Let's find out.
