Help needed from repair experts choosing a used Miele or Bosch in Ukraine!

[holodilshchik]

Hello from Ukraine.
Here in Ukraine, on marketplaces like OLX, there are many used washing machines imported from Germany and other European countries, especially Miele and Bosch models.
I am trying to choose a really reliable washing machine for long-term use and would like to ask people with real repair experience for advice.
The most important things for me are:
прочная механическая конструкция;
Полностью исправная разборная ванна с надлежащей заменой подшипников;
надежный двигатель;
электроника с минимальным количеством слабых мест;
хорошая доступность запасных частей;
машина, которую реально можно отремонтировать даже через 5-10 лет.
I am specifically looking at used machines because new models are too expensive for my budget, and older German machines are often considered more reliable here.
I am especially interested in:
Miele ...... platforms;
Bosch ...... series;
older German-built machines with good repairability.
I would really appreciate your opinion on:
Which Miele and Bosch series are the most reliable and long-lasting?
Which models should be avoided because of electronics or tub construction?
Is it still worth buying older Miele machines today, or are newer Bosch models a more practical choice?
Which platforms are easiest to repair and still have good spare parts availability?
Which models would repair technicians personally choose for long-term ownership?
Later I can add a list of the used machines currently available here in Ukraine, including prices and condition.
Thank you very much for any practical advice and real-world experience.
