It used to be Australia's easiest quiz question: What's our most popular car?
Holden Commodore, of course.
But motorists have been gravitating to smaller cars, SUVs and even dual-cab utes, so the question's no longer a gimme.
For example, if you had attended a quiz night in 2011 or 2012, would you have known to say Mazda3?
This year, the right answer is Toyota Corolla, though the Mazda3 - which comes as a sedan or hatch - is a close second.
The Mazda's slight fall from grace is because it is in the last year of a model cycle, when many buyers wait for the new model.
Mazda has helped to keep sales ticking over by sweetening the price - as is common with run-out models - to $19,990 drive away.
At the same time, the Japanese marque is obviously very upbeat about the future Mazda3.
It doesn't get here until February but the carmaker has been going to the ends of the earth - literally - to get journalists behind its wheel.
During last month's Frankfurt Motor Show, I was lent a 2.0-litre petrol version for a spin in the German countryside.
And, on Tuesday, I was invited to Anglesea in southern Victoria to do a back-to-back comparison test.
But I wasn't pitting the future Mazda3 against rivals such as the Ford Focus or Volkswagen Golf.
The opponent was the current Mazda3.
Each model had two variants - 2.0-litre and 2.5-litre petrol - with the driving done at a test track.
The day was tinged with sadness, really.
The old champ, though game, was never in the race. It was beaten by the flash new colt on most measures - by just a nose or half-head usually - but beaten just the same.
The edges include exterior styling, aerodynamics, interior quality, driver ergonomics, power, handling, steering, weight-saving, body rigidity, fuel efficiency, emissions, ride and cabin noise.
Added to these is the new car's whole suite of advanced technologies. such as blind-spot monitoring, automated braking, smart-phone integration and internet connectivity.
In its connected cabin you're spoilt for choice - 40,000 global radio stations and Twitter, Facebook, email and SMS.
But such features can seduce one away from driving, so Mazda has designed the cockpit with various thoughtful safety features.
For example, a head-up display projects speed and sat-nav information to just below the driver's eye line.
Also nifty is text-to-voice translation of incoming messages, which allows drivers to use their ears rather than eyes.
The distracted driver could be saved, nevertheless, by the smart brakes.
At city speeds, they activate automatically if the driver does not react quickly enough to avoid a collision.
Add up all those edges and the fresh model enters a new plane, looking, feeling and driving like a luxury car. It's that sophisticated, really!
The advances have emerged largely out of two Mazda obsessions - called SkyActiv and Kodo.
SkyActiv involves myriad small engineering efficiencies which, together, add up to greener, more dynamic motoring.
For example, the future Mazda3 has more power and torque than the current model yet sips 5.7L/100km - a whopping saving of 2.6L/100km.
Kodo is the fancy word used by Mazda to describe its animal- in-motion styling approach.
If wanting to get a good idea of what the new Mazda3 will look and feel like, take the Mazda6 or CX-5 for a test drive.
These are the first two Mazdas to get the full SkyActiv-Kodo treatment.
When I was testing a Mazda6 recently, I received two unsolicited "nice car, mate" remarks.
One was from an unlikely source, an old cricketing mate who sells cars - a rival brand to Mazda.
Usually, Dave's acerbic about competitors.
But he liked Kodo.
Must be mellowing.
