 Its been over 12 years since my last bimmer.  There's lots of new technology, but most importantly the fun-to-drive factor is still there.  Adequate power from the 215hp, very comfortable ride, solid feeling car.  Only two disappointments are the Nav and interior storage.  Severely outdated and lacking basic function of search-by-name.  Who decided to leave this out?  Interior storage is minimal.  Space in center armrest is laughable.  Those gripes aside this is a great car.
