FYI, finally got to go to one of these. The folks working there were quite knowledgable, far beyond what you'd expect at a typical dealer. After you check in, you get an overview of the car where you can ask questions, then go for a quick drive. I went at 3pm and the car still had 14 miles of EV range on it. I did notice however that they would run the car in HV charge mode in between test drives (there were no chargers there).
After the test drive, you fill out a brief survey, then they give you a gift (a clarity themed portable battery pack for your phone).
Definitely sold me on this car. The low end torque was surprisingly fun.
