Ok so now that no more Aussie Commodores are being made, the number on our roads can only dwindle. As an example, this week at the local wreckers 4 VEs came in.
The first VEs will turn 12 this year; bear in mind that currently the mean (average) age of a car in Australia is about 10yrs, and the median is about 8.5-9yrs.
I'm looking at starting a long term study into how many Commodores are still out there. By trade I am a high school maths and engineering studies teacher, and a bit of a maths geek as a result lol.
The method will be to use the amount of Commodores listed on Carsales - quick, easy, and you can do a quick search on a daily basis and record the data. I am assuming that the amount of cars listed reflects the amount of cars still out there (to a degree). As dealers tend to only do newer cars, I am removing this bias by looking at private sales only. I will also assume that the general volume of cars for private sale on carsales will remain constant - I can record this too, and apply any corrections necessary.
First data point - 6th March 2018
