I have only seen one Model 3 in person in WA, but I have seen pictures of several on the road or at delivery centers, in several different colors. My son got to drive one a couple of days ago (he used to work at the Bellevue store).
I did visit the new Bellevue Store on Tuesday night. It is definitely bigger, and has a couple panels briefly describing the Powerwall and solar panels, but otherwise is not very different from other stores I have seen.
