I agree. As an avid "car guy" and a student of regulation, I cannot think of any reason for car dealers, as a whole, to be protected in the long-term. I am, however, perplexed with how we should address the possibility of established manufacturers attempting to cannibalize the sales of their most profitable franchises by building neighboring dealerships with their considerable capital.

I believe the California model actually offers a lot of hope: manufacturers can compete, but they must observe a 10 mile radius from existing franchises.
