Andy,
If you only drive 18 miles roundtrip like me they may make sense. There were 2 & 3 year leases available on Volts available for $200/$129 per month.
However, I would never purchase one. It is not a good investment. If you want a classic car that is going to appreciate in value buy a used Ferrari or something like that. Also, I would not park one of these cars in my garage. You do not want to take the chance that it could burn your house down.
The lease deals are up to $299/month for 36 months, so they have backed off from the crazy low pricing a bit.
Great point about the fire risk! I would feel OK running a 10 GA 110 VAC extension cord to a Volt sitting in the drive way.
Oh, well, thanks for all of the insight.
