2025 BMW M Models Summary

To say the BMW M4 CS is a hot ticket in Australia is something of an understatement.

Consider this. There is an even more expensive one, the M4 CS Edition VR46 – at a cool $346,900 – and it sold out in less than an hour. Now, granted, Australia only got four examples, but still, demand was running hot.

That car makes this one, the regular M4 CS, seem like an absolute steal. It's only $254,900 (yes, the word 'only' is doing a lot of heavy lifting in that sentence), and it shares the same upgrades, and makes the same monstrous power, as the VR46 – for Valentino Rossi’s 46th birthday – only it does it for around $100K less.

See? A bargain. At least, that's how I'd be justifying it to myself if I had a quarter of a million burning a hole in my pocket.

So, this or a Porsche 911? Read on.

2018 Subaru Liberty Summary

Subaru's Liberty is probably one of the most recognised badges in the country. Talk to anyone outside of Australia, though, and unless they know their cars, they haven't the faintest idea what you're talking about. It's a mark of Subaru's respect of the Australian market - the company renamed it from Legacy for local consumption - and the power of a brand that's approaching 30 years old.

Just about every Australian reading these words has been in a Liberty of one age or another. Some even remember it for Colin McRae's heroics at the wheel of the blue-and-yellow machine in the early '90s before the switch to another famous Subaru, the Impreza.

The Liberty is now well into its sixth iteration which means time for a mid-life nip and tuck. Subaru has worked above and below the skin to breathe a bit of life into its mainstay sedan.

Verdict

Brutal, bruising and utterly brilliant, the M4 CS will be an acquired taste due to its no-compromise approach, but those willing to take the leap will find a performance car like few others at their disposal.

Verdict

The Liberty has a lot going for it - a great reputation for reliability, it isn't terribly priced (although servicing is a little steep) and has that signature all-wheel drive. While I've complained about the ride and handling, apart from STi and RS-badged versions, that has never been the Liberty's strong suit.

While it might be a shrinking part of the market - and Subaru is a founding architect of the modern SUV cult - Subaru and its competitors still care. The Liberty, like Forester and Outback, remains a stand-out in the sector with a boxer 2.5 and all-wheel drive. Sometimes that kind of individuality is enough.
