At 5:30 on Saturday, about half of the slots (six?) were available. One of the chargers was free, so I used it, even though my car was one stall over from the charger and my car wasn't that low on charge. I asked the test drive employee if that was okay, and he said that if the cord reaches, it's fine. I went into the showroom and offered my key & phone number. They were crazy busy and told me not to worry as long as I leave before 9 (when they want to plug in their test drive car). I got back to the car at 8, and all of the stalls were filled. I think they could squeeze in one more stall if they wanted. They could also use more chargers.
