Love is what defines a Subaru, not gas mileage.
Wow only 15 MPG, that's crazy with today's technology. Is that because you kept your foot in it?
My 1979 V8 302 Thunderbird now gets 20 mpg highway after I de-smogged it.
My 2001 Chevrolet Blazer that is shaped like a brick got 20.6 mpg last week driving to Tennessee and back. The only mod it has is a better exhaust.
Glad you are happy with the MS3. You should write up a brief comparison between the two.
