I've been amazed that the Chevy volt isn't selling more units.
You get 53 miles electric and 42 mpg. Unlike the i3 with rex you can go full speed on gas. And unlike the Toyota Prius plugin, the gas engine is purely an electric generator.
The car after incentives and dealer rebates is 20k. GM also offers 0 down 0% financing over 60 months.
It's a great commuter car as the 53 miles is more than enough to get to work. at work you charge up and you've got enough to go home. If you want to go on a road trip you still have the gas engine.
