Believe it or not _most_ production automobiles have a net lift force on them. This is one of the reasons a well designed spoiler can sometimes both increse downforce (by reducing lift) and at the same time decrease drag. If the car was operating with net downforce, and increase in downforce would increase drag.
I do not know about the 9-5's aero characteristics in particular, but I would gues it falls into the net lift category.
Do a search on :
lift downforce aero cars
And you will see quite a few hits that basically cuncurr with that which I stated above. Sadly, from the quick look I took many of them have the _very innacurate_ description of lift occuring due the air at the top of the wing (or auto) moving faster than that at the bottom and citing a net reduction in air pressure at the top. (this assumes that the air at the top must reach the end of the wing at the same time the air at the bottom does so. But there is no reason why this should be true)
