We bought the Subie for its safety and reliability. I did not do my homework on the performance of the vehicle, nor on its interior space.
The engine is adequate, but the 4AT is a lousy transmission. The car works too hard to find the right gear, and kick-down's are frequent and blatant when the engine is working hard.
The rear seat was woefully inadequate for accommodating a standard infant seat without pushing the corresponding passenger seat up all the way. This led us to trade in the vehicle.
The car was reliable while we had it. No complaints there. The paint quality was thin and there were rattles in the dash that shouldn't have been there for a young car.
Safety, reliability, and AWD traction (especially with snow tires in place).
Ditch the 4-AT. The newer Outbacks hopefully have more rear-seat legroom.
