With all the snow and crap on the road, I can drive 10 ft without the back window and the whole back getting filthy. I've see some other makes of cars with a built in spoiler to direct air down the back to reduce dirt.

Is there anything like that for an Avant that doesn't look dorky or make it look like I am trying to make a Ricer out of it?

I have a roof spoiler but it still sucks dirt onto the back

That area causes any debris/water kicked up by the rear wheels to be thrown up on the rear surface, like a vacuum cleaner sucking up dirt. An Avant has a larger low pressure area than a sedan since the top of the car runs all the way back, hence it will get dirtier. But even a sedan's rear end gets filthy, just not the rear window. That's why there is a rear wiper/washer on an Avant and not on a sedan. Unless yuou can divert a large volume of air, a spoiler won't do much to keep it clean. My '96 A6 Avant has a little spoiler that diverts some air, but the rear end still gets dirty fairly fast in mucky roads conditions.
