If you don't like the Subaru Outback, which has blossumed into a full SUV, and don't want to go SUV then the VW Sportwagen or AWD Alltrack is probably your best option. Remember they are also making an AWD, non Alltrack version of the Sportwagen. They give up a bit of space to the V70, but otherwise are solid vehicles and have good back seat space. They feel high quality and have good handling on the solid VW/Audi MBQ platform. A roof cargo carrier adds a ton of utility. Other European wagons offered in the U.S. aren't nearly as large (Allroad, V60, 328ix, etc...). Engine has decent power and economy is good.
The Sportwagen unfortunately only comes in a manual in base "S" trim, but this trim is well optioned. The Alltrack has VW's excellent dual clutch automated manual, which is a brilliant transmission. My TDI had it, and my GTI has it. Shifts are lighting quick and the manual mode is quite good. It just costs $450 or so to have it serviced every 40,000 miles.
I had a TDI version of the previous Jetta Sportwagen and loved it. I went with a GTI when VW bought my wagon back, only because my wife drives an Odyssey so it isn't our only car. If it was, I would be driving a Golf Sportwagen or an Alltrack again.
