Everyone is wrong, we all know its because the superior engine option of the mighty 3.8L Ecotec V6
Had this old bloke customer with a VN wagon come into my workshop for a rear wiper motor, things odometer stopped working at 727,000km, this was in 2015.
The guy had been all around Australia in it with his family, had done two gearboxes and still on its original Buick V6, the predecessor to the mighty Ecotec, I reckon he's probably pushing up daisies now he was old AF back then, VN wagon is still probably going.
