I thought I'd stick a note in here, considering I'm driving a Subaru for now. Modern Subarus are reliable cars, excellent for their drivetrain engineering. They have always lacked in passenger comfort features, though the latest Legacy/Outback models have made huge strides forward in this department. I don't know how the B9 compares to its competition in that area. One thing that is still an issue with Subaru autos, other than the WRX models, is their lack of power in the low end of the rev range. They just feel sluggish compared to many other autos, including modern minivans. That may bother you, it may not.
I would take a look at the current issue of Consumer Reports, which is totally devoted to autos. Read up, and look at other options before buying. I bought my Outback 6 years ago, and have been pleased with it. More power would be nice, but it's certainly not a necessity for child hauling.
