I absolutely love the 540i 6speed. It has tremendous torque for when I want to go fast, but is elegant and civilized when I have the two infants in the back. I enjoy doing the work myself so labor cost is not an issue, but parts can be more expensive than some other makes. If you're an enthusiast like me, you'll love this car.
V8 and 6 speed. Timeless styling, fits the family well and still corners almost as good as an M3.
A few too many electronics for my liking, but I guess that's what a buyer wants when spending $58K on a new one in 1999.
