Not sure where you get the
Not sure where you get the double price.
For example the Chevy Volt is about 32K with tax credit. Thats with a very nice trim level, compare it to a Cruze then maybe its 8K more for the same trim, but the test drive the two and you realize that the Volt is not a Cruze it drives like an Audi. So for the 8K extra you get a car that drives and feel like an Audi and you save on $100+ plus each month on gas.
So over say 5 years your price diffrence to a Chevy Cruze will be down to maybe 2-3K for that you get a car that drive like an Audi and even better comfort with a silent drive to work.
Over 10 years its cheaper than a Cruze and you get the ride like an Audi and much lower maintenace cost than the rip off thats Audi.
