I built one to match the features of the Volt and the base price climbed to $23.1K. After rebates, my loaded Volt cost 28K.
The focus is a nice little car. I like Ford vehicles. But it's still a buzzy little gas guzzler and it only gets 36MPG highway.
I'm getting 80MPGe in my Volt and drive 20K miles a year. With free workplace charging (from a Solar array BTW), my daily 79 mile commute costs me $1.03-1.50 in my Volt, depending on the weather. At 36MPG highway and current gas prices, which are historically normal, that same commute would cost $7.26 per day in the Focus.
I keep my cars for a very long time. My last car was a 2004 Sonata. If I were one of the many people who swap out their cars every 4 years, the Volt would certainly make much less sense.
