The truck might be useful, but they don't give a price for it. The car/trike seems way, way overpriced for a regular person to own, since you still have to have a regular car if you want to travel somewhere beyond 30 miles away by freeway. It would be a great car for things like delivering newspapers and pizzas and local commutes, but it's way overpriced for those uses. If they could drop the price by over ten thousand dollars, and guarantee it will keep you warm in the winter, it might be a good idea.
