I purchased a new Fit in 2010 (base model, manual transmission). At the time, I also considered the Corolla, Matrix, Yaris, Prius, Civic, Elantra Touring (wagon), and a few other vehicles.
Last year Consumer Reports ranked the Fit as the car with the best value (factoring in cost, ratings, and reliability). This year they ranked it second to the Prius. However, it did not score well in a new side-impact (offset I think) crash rating that was added this year, although previous crash test results were good.
I have been very happy with my Fit. It perfectly meets my needs. If something happened to my car, I would immediately go out and buy another Fit. I am a little apprehensive about the 2015 redesign, because people/companies often make things worse.
The Fit is peppy/nimble for a car of its class. It has a lot of cargo room. I can fit my bicycle in the back without removing the wheels. The interior is simple (at least for the base model), which I like. It has very good visibility. It is not a quiet car in terms of road noise, although this does not bother me. Reliability has been perfect, although I have only 13K miles on the car.
I get great gas mileage. I average about 42 mpg, which is considerably higher than the ~32 mpg ratings from the EPA and Consumer Reports. And my driving is almost entirely city (suburban), although admittedly I have a very "light foot." I constantly watch for upcoming stop lights and coast in neutral when coming to most stops. I've never taken it for a full tank on the highway, although it appears to get close to 50 mpg. I drive 60-65 mph in my relatively rare trips on the highway.
Great car - for me.
