In thinking about what BMW would be perfect for a week-long holiday adventure in the upper Midwest of the US, there are a few that immediately come to mind. My own E61 5 Series wagon certainly fits the bill. But of course we needed to test something new and the wonderful F11 5 Series wagon isn\'t coming stateside. There\'s the line of SAVs - specifically the X3 and X5 to consider. However the X3 was quickly deemed too small. The X5 would work but there\'s something a little expected about it. Then it hit me. Why not the biggest of them all; The 7 Series?
