Yep, both my XC60s have had 'orange peel'.
I did some reading on the subject and perceived wisdom seems to be that the US forum was right and that all cars have 'orange peel' to some extent.
Apparently it can be lessened by sanding between paint coats but that is only done with high-end cars, and Volvos don't come into the high end category.
Have a look at this article:

It's lengthy and quite in-depth but worth the read.
