I bought my 2015 Fit in
I bought my 2015 Fit in August, and agree that it is going to surpass the Civic. The Fit has better rear leg room than the Civic, more trunk space (this past week I had 4 roller board suitcases plus backpacks in the trunk with the shelf in place and no obstruction of view), and a better stance. The versatility of the "magic seat" sets it apart from all other hatchbacks on the market, and the build quality is excellent.
The CVT automatic transmission gets good gas mileage. I've hit as high as 44mpg on road trips, and don't drop below 30 in city driving; but it does lack in power. I didn't drive the manual version, but I'd guess that it is more responsive.
That's the opportunity for Honda: build an Si version of the Fit. That would top the Mazda Speed 3.
