Without question, one of the most buzzworthy topics surrounding automobiles this year has been plug-in cars. Issues like fuel price instability, dependence on foreign oil (or oil of any sort!), and the environment have stirred the imaginations of many people. Could we really rid ourselves of oil-powered transportation? Could America really free itself of its addiction? At the very end of last year, the Chevrolet Volt and Nissan Leaf went on sale (retailing at $41,000 and $32,780, respectively, minus a $7,500 Federal tax credit), finally bringing plug-in transportation to the masses and, plug-in fans hope, heralding a new era in automotive history.
