I bought my Outback Wagon new and after 90,000 miles I can say it is the most reliable car I've ever owned. I replaced the clutch at 80,000 miles and apart from routine maintenance (oil changes, wiper blades, headlight bulb, tire rotation, new battery at around 60,000 miles) that has been it. Even the original Wilderness tires did not need replacing until 75,000 miles.
AWD!! I live up a steep ridge in a snowy area and have never worry about getting stuck.
The only problem has been that the weatherstripping around the doors has come loose several times, and the windows don't seal as well as they should (one window seems to slip imperceptibly - it doesn't seem to be open but you can hear wind whistling through it.)
