Depending on the length of your commute, you might want to consider a Volt.
I got a 2012 Volt Premier fully loaded with a 12 month dealer bumper to bumper warranty for 12 grand. You didn't say what part of Florida you're from, but depending on the market and your negotiation skills you could get a low mileage 2013 or even a 2014 Volt for under 15k, and they get more EV mileage than mine. I had to drive from Lakeland to West Palm to get mine, but it was worth the drive.
I love it so far, it looks and drives like a nice car but I don't use any gas. I haven't even noticed the extra kWh on my electric bill, and I have zero emissions. You live in a perfect state to drive one, I get over 150 mpg in mine
If you come through Lakeland you can check mine out
