Nobody wants to buy new cars that are tied to the grid. I predict the market for used cars is going to get much much hotter.
A 1972 pickup truck would be perfect for me. No/few electronics, nearly EMP proof and I think they run on leaded gasoline just to piss off enviro-whackos (not that you find leaded gas). Plus, I think I would be styling with fancy window vents and gun rack. It would be nearly impossible to steal with three on the column.
