Guess what, New Zealand? You will have the chance to own Australia's first supercar, the HSV 427. This 7.0-litre V8 monster is an ultra-exclusive muscle car that makes 375kW/640Nm and will rocket to 100km/h in 4.7 seconds.

Just 427 are being made in total, so the W427 (the name comes from the engine size in cubic inches) is a guaranteed collector car. A mere seven are earmarked for New Zealand.

So you could definitely buy one. Or maybe you just buy a 6.2-litre GTS sedan instead. And have change for a Commodore SS wagon to cart the kids' bikes around in. And an Astra turbo to pop down to the supermarket in.

The W427, you see, has a recommended retail price of $195,000. It's very rare. But that's a really expensive Holden in anybody's language.

Add a couple of options like the rear-mounted DVD player ($2000, even though it's standard in a Calais V) and sat-nav ($2900), and you have created a $200k Commodore. Remarkable.

Is it worth it? I really don't know, as the Kiwi motoring media haven't yet been invited to battle with the beast. But I await the call. Like, I'm beside the phone. Right now.

But put it this way: the Aussies are raving about it, the first year's supply of Aussie cars are sold out and the whole W427 phenomenon seems unstoppable at the moment.

Here's the big question: is this megabuck Commodore a milestone for Holden/HSV or simply an inspired flash of madness?

What this means to you: That $90k HSV GTS - formerly top of the performance/image tree - suddenly looks like second best.
