No, no spoiler. I was thinking of the factory spoiler that has a space between the spoiler and the roof. But I couldn't tell if, in that space, the air is directed downward to clean the rear window.

I really am stumped about what to do. I suppose the best first step is to install VG and see if they are effective enough at cleaning the rear window. If not, then take the next step with the rear deflector. One last concern with the deflector is how much it will mess up my gas mileage; I want to do things that increase mileage, not decrease it...
