I agree with you, we have friends next doors, one bought a model Y and the other an ID.4. The quality of the model Y painting is really bad, it is brand new (delivered 3 weeks ago) but already looks old.
But it is maybe deliberate. I am in Germany, I have no ideas where the model Y is produced but maybe the type of painting we have normally in Germany is different than the type of painting in other parts of the world.
