My '06 Subaru Forester is far more polished and sophisticated than the '05 Honda Civic EX I just sold. It is equal in quality workmanship to the '04 Toyota Prius I owned before that. The car is simply incredible -- the best combination of safety, reliability, cold weather stability, economy, comfort (surprising legroom for a tall driver) and performance. It is the best bad weather car I know of. I hate traveling when I have to rent other cars and can't wait to get home to my Subaru.
Stability in bad weather, safety, smoothness.
Maybe another mile or two MPG gallon, although 29 hwy mph for an all-wheel drive is just fine.
