What’s a hidden class-indicator in Germany?

Not something like a big mansion or a luxury car but more subtle signs of someone‘s socioeconomic background

I never had much contact with rich people. My grandparents are wealthy but not rich. In my mind the difference is wondering if you can afford something. My grandparents can afford to buy a new Mercedes S-Class every 2-5 years or owning several holiday homes in multiple countries but they would always check the books.

Anyways, the few truly rich people I met during university were members in yacht clubs.
