Hi, I live in Milicz, nearly 60km from Wroclaw, Lower Silesia.
You're right, Citroen XM is very rarely seen on road, almost as rarely as 2CV. At the moment I do not know anything about any other XM in my city. Some time ago there was one 2.5TD Y4, but from what I know, it has been sold after timing belt fault.
Much more popular is the Xantia and is very easy to see one on the road. I personally know the owners of four Xantias who lives near me but only one owner of XM Y3 Break 2.1TD in one of near city. Also, there are at least two Xantias in my city, whose owners I do not know.
We even have a few clubs and forums for owners of Citroens in Poland.
Returning to the 2CV, next year in Poland will be held 21st International Meeting of 2CV Friends:

I added pictures of my 2CV (which was 4 years ago renovated), also silver XM Break which is in excellent condition and the green Y3, which suffers because of his age, but most likely in the spring goes engine overhaul and some other treatments.
Next one is my brother's Xantia. This was a much neglected by numerous previous owners. We've fixed a lot of the things and keep it in good mechanical condition. I think it is worth it, Activa is a very rare model.
Still do not have any photos of the third XM because it was recently purchased, but it is in good condition and requires only a basic review and some minor repairs. No later than the spring will be fully operational. I do not hurry because most of the work I have done on the outside. Garage is occupied by 2CV while two-column lift is outside. Now it is too cold and windy to work
I hope that "my" English is understandable. I did not have far too many opportunities to use it
