Erik,

One other thing you might consider: Required octane.
I believe the turbo Subaru's require the expensive
high octane gasoline.

The Volvo V70 wagon with the five cylinder non-turbocharged
engine tows well and the Volvo web page shows a 3,300
lb towing capacity for all their engine variants (in
America). A friend previously had a V70 non-turbo,
front wheel drive wagon and pulled his glider with
it. I drove it a few times, with and without the glider
in the trailer :-) and it drove nicely. But, the
thing required high octane fuel. On one retrieve,
he left the car with the tank mostly empty. I was
not a happy retrieval person, so I ordered a bigger
steak and a couple of glasses of wine upon our eventual
stop for dinner.

He is the pilot who now tows with the V6 RAV4. The
Volvo got taken out by a wreck (nobody injured, and
the car didn't look that bad, but the insurance company
totalled it out.) The V6 RAV4 requires only regular
fuel.
