The world's second-biggest vehicle maker; depending on the month it's sometimes the biggest; leading the race with sales and model variety.

It has 14 distinct models on the Australian market representing 95 versions. Add another 13 for the Lexus label. Populate indeed.

Look closer and there are seven Aurion models; compared with five from Falcon and Commodore's six; to fit most wishes and wallets.

Hang the expense because today we're in the $42,500 Sportivo ZR6, a model only beaten in the Aurion price stakes by the Calais-chasing Presara at $49,990.

Let me digress for a moment. Where is Toyota finding these names? The Aurion line-up starts with the AT-X, then the Prodigy, then two Sportivos (SX6 and ZR6), the Presara, then the two sports models, TRD3500S and TRD3500SL. What's wrong with G, GL, GLS and GLZ?

Anyway, the ZR6 gets more kit than the $4000-cheaper SX6 in a desire to upgrade its sporty looks to appeal to buyers wanting a bit of luxury.

The Aurion is built on the four-cylinder Camry platform, though there are big changes to the suspension, steering and brakes to cope with the 3.5-litre V6 engine.
