I love this car. I traded in my Fiesta last year for my C-Max, and as much as I loved the Fiesta, and I did, the C-Max makes it feel like a toy. The transmission is so smooth, it's unbelievable. It drives so nicely, the interior is exceptionally well laid out, good storage options - the centre armrest is a bit of a block hole though. The car is extremely quiet, even with the ICE running.
The car will teach you how to drive, and what you can do to be more efficient which is very cool.
My fuel economy with it has been great, averaging 4.8L/100 over about 15,000KM so far but good luck trying to hit Ford's estimated 4.2 in the city which is why I gave this 4 stars there. Even to hit 4.8 consistently, I'm driving pretty conservatively.
