There are also many antique dealers and markets in Germany. Most of them are specialised, e.g. in art objects, technical equipment or building materials. There are also auctions, although these are increasingly moving online.
Yes, I myself like to buy second-hand and with the charm of past decades.
Auch in Deutschland gibt es viele Antik-Händler und Märkte. Sie haben sich meist spezialisiert, z.B. auf Kunstobjekte, technische Geräte oder Baustoffe. Es finden auch Auktionen statt, wobei die sich mehr und mehr in den online-Bereich verlagern.
Ja, ich kaufe selber sehr gerne gebraucht und mit dem Charme vergangener Jahrzehnte.
It's nice that there are so many antique shops :) There is a need to specialize in so many areas in antiques that it is not possible to know all of them. Usually, specific people who are experts in some specific fields are consulted about their area of expertise.
As you said, most auctions are starting to go online. This gives it a chance to appeal to larger audiences. It is very advantageous online, but I am in favor of experiencing that atmosphere face-to-face :)
