I pretty much agree with Michael, except I don't know which Subaru you are talking about. There is a 2.5i wagon for the Outback, Legacy and Impreza. I can talk about the Outback from experience and the Legacy by similarity. The passenger space is identical, but you will find the access to the rear section via a hatch a lot more convenient than using a trunk. I found that I gut just what the window sticker said as far as mileage, including 28-30 MPG on the highway and 22-23 MPG around town. I do not believe the car is a California-certified ULEV (Ultra Low Emission Vehicle), as the Honda's are. ( do see the claim, "Meets the strictest emissions standards for gasoline engines when equipped to meet the California Partial Zero Emission Vehicle standard, although I have no idea what that means.) The Legacy and Outback are very safe cars in both accident avoidance and crash safety, as they are rated tops in crash safety by NHTSA and IIHS, so this will help keep your insurance rates down, but we have no way of knowing what YOU will have to pay.
I like the car very much. I am in the very weird position of having bought two Outbacks in less than a year. I just had to get the 6-cylinder. However, instead of trading in the 2.5i, I passed it on to my 33 year old daughter. I was very happy with the car and very confident in its safety and other attributes so that I knew she would not be getting "stuck" with a lousy car. I think the 2.5i Outback is an excellent car. I think the 3.0 is a better one, but the 2.5i is still an excellent car. :-)
