BMW G31 2020 full equipment advice needed

[elcrni]

Hi All!

First of all, my Deutsch is not so good yet and i am not sure English is ok, if now please remove the post! Thank you.

So, i am currently driving Audi A6 C8 2020 avant quattro, with 96k km on it, i had it for a year and i started hating all those displays and lack of physical buttons, interior feels cheap and since i bought it i had random problem, random parking camera failures, parking sensor beeping when there is nothing around the car, and quite a few other random "error" messages that would go away the next time i use the car. Authorised Audi shop says everything is ok...

In 2013. i bought Audi A4 avant with 180k km! on it, drove it for 10 years without a SINGLE issue, thus i went with audi again... but i just dont like it and dont feel its reliable.

My next car will be a BMW 520D G31, i have found a couple that i could trade my Audi in, range of price 40000-43000 EUR, with full equipment, glass roof, leather, adaptive LED... and with 70-80k km on it

I am fully aware that i can get equally "bad" car with G31, with similar, same or worse problem than with A6 and thats why i wanted to ask is there anything i should be aware of, any known issues?

Specifically what worries me, is the glass roof and schiebedach as i see some people complain of it sticnking, rotting and leaking...

Any advice would be highly appreciated.

Many thanks

P.S. i am buying a car in Austria, Salzburg area.
