I have a 2012 manual transmission Fit that I tow from time to time, and use for day to day transportation. I prefer manual transmissions, the choice was not about towing, it was about finding a car I could shift myself.
Fit vs alternates like Fiesta, Focus, Cruze, Versa etc, I liked the people vs cargo flexibility of the interior, and the great visibility of the large windows, which adds to the ease of getting around in crowded places and finding parking.
I find the Fit a bit underpowered. While it can get to highway speeds on most on-ramps (driver only) it struggles with things like high-speed passing maneuvers on two lane roads, and I really feel the difference when four passengers and their luggage increase the weight by almost half a ton. 120 HP is zippy for an empty car, 160-180 HP would be more to my taste (turbochargers, anyone?).
Most recent example of the power issue, I recently made a trip to north-central North Dakota in strong winter winds. First day of the trip through Kansas, I had a tailwind pushing me, got 44 MPG for 400 miles of driving, hardly any wind noise and a soft buzz from the engine. Second day out I was on 80 MPH speed limit Interstates, 20-30 MPH northerly winds, so the car was struggling to reach the speed limit, effectively 100-110 MPH against the wind, pretty much full throttle to keep up with traffic. Of course a small car flat-out is still more efficient than a big one at the same speed, so I managed 20-22 MPG running full throttle into headwinds.
This is not just about the Fit. Most subcompact cars sold in the U.S. are similarly powered. Think about how you are going to use the car. If just around town, subcompacts are fine. If extending the usage into road trips on high speed highways, think again about the limitations. I have a long history with small cars, my first was 40 HP and it got 40 MPG, but would not overtake a car going 50 MPH in a 60 MPH speed zone, so I replaced it with a slightly larger 96 HP compact that got only 30 MPG but could make a safe pass at those speeds.
Currently looking closely at the turbo-charged sporty Civic models (180-300 HP) but I would really rather have a 160 HP Fit.
