The current Euro-spec 5-Series wagon makes me very jealous as an American.
The old 5-Series wagon from the
1989-1994 era was pretty amazing (I had a 1990 5-Series sedan immediately before the 3-Series wagon that I drove into the ground) because it had a normal sunroof in front and an enormous second one in back, making for basically open-top driving. There was also a very rare M version of that model which, to my knowledge, was the only M wagon BMW has ever offered. The next 2 generations of 5-Series wagon both were offered in the U.S.; I think the current one you picture here is the first and only one that hasn't been.
