200 miles daily commute in a Chevy Suburban is not practical, so I got a Subie. Best MPG at 29,9, worst at 26. Without exceeding speed limits (by much) the Forester "saves" more than 50 hours per year due to superior cornering on the mountain roads I travel. After driving it for 12,000 miles, I just regret not spending a few thousands more for a turbo.
Safe cornering at high (legal) speed. Good gas mileage. And of course - NOTHING beats a Subaru in snowy road conditions.
Cruise control works great going uphill and in the flatlands, but not going down the mountain - on down slopes you need to turn it off or risk a speeding ticket.
