stjohns -- we're big Nokian fans -- and the Hakkas are wonderful on our BMW. We don't need studded tires, but I'll order the Hakkas when we take delivery of the new car (although you guys further out West are getting all the snow these days).
Used a set of Blizzak WS-80's on my '05 Mz3 last year and they were wonderful. Got a set for my new 5 for this year........ so I'm ready whenever winter decides it isn't taking the winter off.
