Interesting site, with some good statistics, thanks for posting.
For fun, I did a search of Mustangs 2015 +, that are still registered.
We were told that there were around 20,000 plus, 6th Gen Australian Mustangs that have now been sold.
Yet only 15,175 are still registered if this site is to be believed.
Maybe, 5,000 or so have been written off in accidents.
