We took delivery of a 12 Focus SEL in June 11, the car now has 24k miles on it.
The DCT transmission has been perfect, it is very smooth and provides quick and precise shifts (3 people i work with have them and are happy too). We didn't get the touch screen MFT, just the basic voice command Sync. Other than butchering some names in her address book it has been trouble free.
The thing that impresses me is how quiet and smooth the car is going down the road. It is also quite peppy and easily walks away from Civics, Corollas and Elantras. It is about the same as a 2.5 Mazda 3.
If you keep the speeds between 60-65 we have gotten as high as 43 mpg on the hiway but hiway mileage is more typically 38ish. We live in suburbia with a minimal number of traffic lights so our around town mileage is in the 33-34 mpg range (never had a full tank average below 30). The Hyundia has been in hot water for over stating the mileage claims of the Elantra so don't expect it to be any better than the Focus.
The MK3 Focus consistently places at the top of the heap in compact car comparisons. The Elantra usually gets knocked for road noise and handling (BTW, there is a Hatchback Elantra now). I know nothing of the Fit, can't get past the looks, but I had a 11 Civic for three weeks while my car was in the body shop and it had to be the most mind numbing car I have ever driven. I have had Corollas as rental cars on at least a 1/2 dozen occasions and it is almost as bad as the Civic.
If you are still looking you owe it to yourself to try the new Dodge Dart, Kia Forte and Mazda 3. I drove the Dart with a 6 spd manual and 1.4 turbo, just not enough power for me. It is roomier than the Dart, handles as well and has great styling. The Mazda 3 was our second choice to the Focus and we primarily chose the Focus because my wife didn't like the Mazda salesman.
My interests for a daily driver require a lot more power. I decided to replace my 03 turbo PT Cruiser late last year. The contenders I considered were the Focus ST, Mustang V6 with performance pkg, Subaru WRX and MazdaSpeed 3 (unfortunately the Dart GT isn't available yet). All of these cars can be had for mid $20Ks. I could have been very happy with anyone of them after testing them but the ST got the nod because of the better mileage rating. I picked up my ST on January 2nd and now have 2500 miles. I haven't had the car on a trip yet but in the same suburban driving as my wife I have been getting 28-29.5 mpg which I am happy with and is about 6-7 better than the turbo PT it replaces.
