I really, really recommend reading The Millionaire Next Door (I have no affiliation with it. It's kinda old-school, but in no way out of date.).
Almost the entire book is about how luxury goods are NOT consumed by rich people, but by semi-struggling middle class people. (BMW's, Rolex, premium liquor, etc.) (Or at least people who have to go in to debt to consume these things.)
(It's also about how rich people DO live, choose to buy stuff, negotiate, etc.)
Everybody in this thread who's saying, "duh, cars aren't supposed to be an investment," are technically right. And everybody should indulge in things that really make them happy. If cars are your thing, go on, do your thing. It's all good.
But in the Millionaire Next Door, it goes over how cars are an especially precarious purchase for most people, as they just really eat up a lot of money over time. For most people, even non-luxury car purchases require a loan.
Cars might be more dangerous for us than say Rolexes, because most of us think "well either way I have to have a car, might as well get a _____."
Anyway, maybe this article wasn't the most persuasive case, but it is true. Most rich people don't have fancy cars, or probably fancy anything.
(In the Millionaire Next Door, it says we get confused by this because there are a famous outliers who show off their wealth, so we incorrectly associate wealth with luxury, when they're rarely related.)
