I would possibly buy a used Chevy Volt, because of its batteries that I can use as an emergency storage device.
When the SHTF Volt owners will put the cars up on blocks, feed it with solar panels, wind generators, hand cranked alternators or even dog treadmills, just to charge it up so they have a massive battery for their puters and cell phones in mommas basement.
I saw a 3 year lease offer in my Sunday paper.
They are basically giving these things away. I only have a 9 mile commute. It could concieveably work for someone like me. I can see how some people might lease these cars but not want to own it. Also, if you have a big pickup truck that you want to keep to tow/plow/work, etc.
