Easily the best cornering car I have had in a long time. I found myself taking roads with more corners because I knew it would be fun to whip the fiesta around them.
Cruising at 75 MPH for a road trip I got 40+ mpg. Around town I have got around 30 in mildly spirited driving.
The car is extremely solid. The doors "thunk" like you would not expect from a small car. I got red leather seats, and it is actually pretty nice leather. For an $18000 car, I feel like I got a steal.
For as well as it handles, I would expect the Fiesta to have a stiffer/rougher ride. But it has an excellent ride.
It is a great value.
