Every car I've owned has been cheaper than the previous and honestly these days I'm mostly public transit. But at the same time, I've become many times richer between each car purchase.
I love the non connection and unpreciousness of my possessions - how profoundly and easily replaceable they are and how detached I am from them.
At the end what is wealth other than excess of liberty and freedom. An ability to purchase luxury without much concern for the cost is at its highest form when someone can also dismiss most of the luxury as frivolous and not purchase it at all.
