Here’s the article:

The author is co-founder of a site that tells people they can make money from buying classic cars, so he definitely has a motive to convince people that it is very profitable. As examples, he shows 6 models of sports care that have doubled in value, or more, in just one year. Clearly that seems fishy.

Here’s the problem – he didn’t take into account the age or condition of the vehicles. And they are all rare enough that looking on a particular day can offer a great variety in prices.
For example, Datsun 240Z. He says they were selling for $42,000 in July 2016 and $98,000 in July 2017 (funny how he using July numbers for a November issue…).

I look on carsales.com.au today and there are 11 for sale, ranging from $21,000 to $80,000. The average is around $55,000.  Some have done 100,000 kilometres, and some have done just 2,000. Hence the big range in prices.

Or the Nissan GTR R34 V-Spec II. Sounds like a very specific model. $61,300 in July 2016, and $200,000 in July 2017.  Today there are none for sale.  But plenty of R35s, but I guess their improvement in value wasn’t as impressive.

Clearly he has cherry-picked models that happened to have a randomly higher value when he looked. The only true way to determine if this is good investment is to track the prices of individual cars.
