Now that Tesla Motors [NSDQ:TSLA] has become a real carmaker, albeit a young one, it faces entirely new challenges:
* Can it deliver a steady stream of Model S vehicles to the backlog of what it says are more than 10,000 buyers who've put down deposits?
* Will the Model S be reliable, and if early cars have any quality issues, can the company rectify them quickly and painlessly?
* Will the mix of orders skew sufficiently to high-end models that the Tesla Model S range overall provides a healthy profit margin?
* And, can sales of the Model S--5,000 this year, 20,000 next year, says CEO Musk--generate enough revenue to cover not only its costs but future model development?
