Good luck trying to purchase one without a waiting list.
In many areas of the country there is still a waiting list for the Prius, which has been out 10 years and still relies entirely on gasoline.
As more electrics become available, demand will go up. The majority of the population still has no idea that electric cars even exist outside of the golf course. By 2010 gasoline should be pushing $5 a gallon, maybe more. Once people find out about electrics, and more affordable models become available, there will not be any way to keep up with demand for a long time to come.
One the other hand, you'll soon be able to purchase a used Tahoe or Expedition with low miles for under $1000. I've already heard that many dealers are simply refusing to take big SUVs for trade in because the know they can't sell them.
The next few years are going to be very interesting for the car business.
