Wonderbar:

 A successful automobile company is much more than just selling cars. It's about reliable parts and service, dependable suppliers, dealership proximity, accurate trade-in values, a vibrant used car market and volume sufficient to pay off investors and invest in research and technology. Ask yourself, does Tesla have that structure now, or in the foreseeable future?

The answer to your questions is no.  Do a search for the lack of after-sales service.
