What is the difference between an decent apple on the tree that nobody wants and expensive apple on the Tokyo market? Some things have their purpose and gain value because of that. And some things are valued because we give them value.
In simple terms Ferrari Berlineta when was new had a price of 300k today you can find unused ones for 900k ( producing stopped in 2017). Yes it is maybe one of the last aspirated w12 Ferrari in the world and maybe there is his value. Is it better than a new model, no, but why he got that value now? Well we gave him that value, because it's becoming increasingly rare as time passes.
