The Wikipedia article needs updating. There is still a dealership law issue Colorado. Tesla had one showroom when the auto dealers noticed that Colorado law didn't explicitly forbid manufacturers selling direct, so they lobbied up a quick fix to the law. Tesla was grandfathered in to forestall the obvious Bill of Attainder lawsuit. So -- no "more" manufacturer-owned dealerships were allowed. This restrained Tesla for a while until it was observed that there are plenty of existing dealers who have multiple dealership locations, but only one dealership license. Oho, said Tesla's legal people -- we can play that game. So they are building new showrooms all over the state. I expect the dealer lobby to try to "fix" that soon, but I've been talking with my state rep and senator about that (and giving them demo rides).
It would be nice if they started building service centers too, but so far they are all in shopping malls with no room for a service department. They definitely need a western slope location.
