the MSRP of a 2013 Volt is $31,645. The trade-in value of my 2000 Ford F250 4X4 Super Duty turbo diesel is currently around $6,900.
So, at $4.12/gal for diesel and 17 mpg, if i DON'T buy a Volt, i'll have saved enough to drive the trusty ol' truck another 102,103 miles for the equivalent of "free".
Face it. Volts are primarily for the environmentally obsessed, and favored crony capitalists like Immelt.
