Anyone who has to show off here with a rare natural stone has other problems.
You can get that feeling, but I think it's too simplistic.
It's all relative. The nurse with a brand-new Dacia may also be proud of her achievement and tell everyone about it. Someone who can't afford a car at all might find that arrogant and exaggerated. Who knows. I would categorize myself as upper middle class, but for example, I have no interest in cars. I don't understand why someone would spend 50,000€ on a BMW, which ultimately just drives from A to B. Sure, nice car, comfort, materials. More power than my ride. If I had 50,000€, other things would come to mind rather than buying a car. But there are also people who already have everything they need. Especially older people, in my experience. Or they have so much money that the price simply doesn't matter. They always ask for the best, because why would you want less.
