Do you want one? I want one. But the Tesla Roadster all-electric sports car, rumored to be coming out early next year, is sold out already.

The firm was started in the summer of 2003 by engineers Martin Eberhard (former CEO) and Marc Tarpenning in San Carlos; Elon Musk -- former PayPal president, and now chairman of Space X, who can afford just about anything -- is also now chairman of Tesla Motors.
