I just did a quick search and 2 things that I found so far that the 328 xdrive classic line has that the regular 328 xdrive does not is leatherette and only 17" wheels........and if as photoman has mentioned that it is the same as the baseline 328 xdrive from the US there are no sport seats, no xenons, and no moonroof, so it seems to be pretty stripped down but a decent price.
