This is gonna be a long post, so bear with me.
I was in the same boat where I questioned reliability vs cost and local vs import when i had to get a car for my old man. He's not as mechanically minded as I am, nor does he have the patience to shop around or modify his car.
We ended up picking up a 15 year old Cefiro, which was completely bog stock... even had the doileys and log books n all. We got it with 40,000K's on the odo (genuine too, with books and dated receipts to prove it). As soon as it arrived we did a aircon retrofit, and did a 100,000K service on it (just cos it was so old and I wanted my dad to have a car that would'nt give him trouble). In the 5 years he owned it, we had to changed the shocks cos they wore out, the sparkplugs a few times, the alternator cos it wore out and some door lining rubber that came loose. My dad chammied it every time it got wet when he parked it in the garage and topped up the battery every fortnight and got the oils changed on the dot every 5000 K's or every 3 months whichever came first. The car never gave us any grief.
Then someone reversed onto the road he was driving down at 70 k's and he wrote off the front of the car. Insurance wrote off the car, and gave him a payout. Shaken up, he insisted on buying something local so he went out and bought a new commodore. I've since bought the wreck, fixed it up and the ceffy's still going strong with about 170,000 K's on the engine.
In the 2 years he's owned the commodore, the auto gearbox shat itself and needed to be replaced, the fuel tank sprung a leak around one of the seals, moisture buildup in tail light, car's gone back to base about 3 times due to problems with the ECU or wiring, air con stopped working 2 months after purchase and got fixed like 2 trips to the service centre later. All fixed under warranty but WTF... I could cobble a more functional car together using my McGuyver skills, a rubber band and some chewing gum wrapper. And I knoew these problems aren't attributable to wear and tear, plus I know how well my dad treats his cars.
Anyone who bleets on about aussie standards and quality can suck the big one. as far as I'm concerned the great aussie dream turned nightmare a long time ago when the bottom dollar became more of a concern over producing great cars that could withstand the average aussie thrashing. That is if you can still buy an aussie made car, seeing as half the shit peddled by Holden comes out of Korea.
The only "aussie" car I'd buy now is probably a Ford Focus or Ford Mondeo. Because neither of them are engineered in australia, they're basically euro's.
Needless to say, dad's gonna be buying an import when it comes time to sell the commode. Which will be soon... hopefully. The way I see it, it'll spontaneously combust about 30 seconds after its warranty period finishes.
I'm working him up to a nice M35 Gloria or F50 Cima... maybe a JZX110 Varossa or soemthing if it becomes available.
