I drove a friend's 325xi last week. Sweet ride but it was an automatic. A manual is better for hypermiling. You asked for an opinion on vortex generators- personally, I don't like the looks and they may not help, despite the manufacturer's claims. The roof line has a nice curve and is very smooth. I wouldn't do anything to disrupt the airflow. Just my 2¢.
