This is my third Subaru wagon. It's been very reliable during the 4.5 years I've owned it. The only non-scheduled maintenance item I've had to perform was the replacement of a malfunctioning anti knock sensor. At 70k the engine is not as strong as it was at first, but still runs strong. Both my previous wagons (GL and Loyale) were purchased used at about 90k and driven to 160k. With regular maintenance Subaru wagons will serve you a long time. They get good gas mileage too; 26-28 mpg on my current Outback wagon. There's plenty of space to haul cargo and luggage too. Don't hesitate to buy one!
AWD is great in the snow. Heated seats are the best in cold weather.
The passenger side visor bumps into the auto dimming mirror: make the visor smaller! The driver's seat is uncomfortable on long trips. It needs to be upgraded. The front end develops a shimmy from disc rotor wear after a couple of years: this is consistent on all 3 wagons I've owned.
