I have a 100-mile per day commute. Car-pooling and public transportation are not an option. If my primary concern is cost-savings in the long run (over style, comfort, etc.), what is the most economical car to own for such a purpose?
The drive is almost completely interstate highway driving. 70 mph all the way.
