The tax benefits are definitely the attraction. Some states offer tax credits in additon to the Federal tax credit. In Oklahoma, for example, the state tax credit is 50% of the purchase price of the street-legal electric car (or cart). It works out so that a street-legal cart can be almost free with the tax credits. Of course, the registration and insurance costs, will be higher. Also, since delivery and registration is required in Oklahoma, it would have to be transported to TV, another approx. $800 cost. I looked into it, but decided I didn't really want a street-legal electric cart that goes 30-40 miles and takes 8hrs to recharge. I am holding out for the new technology, which, if proved viable, will eliminate those disadvantages. Until then, I'll stick to gas, even withouth the tax credits.
