I found this article while doing some research on electric cars; http://www.popularmechanics.com/cars/hy … ar-panels/

Ok forget the 6 seater golf buggy that would not be registerable I think
The Tesla is way over the top price wise, The I Miev is around $52k http://myelectriccar.com.au/mitsubishi-miev/ so even if the fuel costs are zilch I don’t think a break even point is within the life of the car. Remember unless you have a solar plus battery all the charging has to be in the day which is when most need the car
But it would be good to be able to give fuel excise the bird!
