Well, I would be more thinking of the Nina as the Karma is already in production and the Nina is still in the design stage. It is hard to wait...and see what happens. I would think the cost of switching batteries mid stream would be out of the question, but I have been known to be wrong on many occasions. I am in a waiting game here to see which vehicle will be my first EV or PHEV. I will support a company I have an investment in.
