Holy depreciation, Batman!
Isn't this the free market telling us what the car is actually worth? There must be a market for 100%-electric cars at just under half the listed price. At a low enough price, I might purchase one myself for the toodle-around-town "other" car.
Now, a truly entrepreneurial car company would figure out how to do this and do it, but Government Motors will continue its central-planning-command-and-control paradigm, as long as it makes the crony capitalists and the socialist-environmentalists happy.
