For me, the 11 miles of range for the Plug-in Prius is the killer. My weekday commute is 50 miles round trip. Of plug-in hybrids, the Volt is still the king of EV range. If I could afford a Tesla, I'd go get one, but the price is just a little more than I really want to spend on one car.
I have yet to pay more than $23K on any vehicle and I hope to continue this streak as long as possible.
