I asked for - and received - an overnight test drive. We negotiated and settled everything else first. But I wanted to make sure I could charge it at my house with just the Tesla Mobile Connector and that it fit in my garage. The Model S is a deceptively large car. I also ran it up to a nearby supercharger to see what that experience was like. There was nothing about payment or estimated cost on the screen which I thought was a good sign about Free Supercharging. I realize in hindsight I could have accidentally charged the previous owner a few bucks worth of electricity. Bad form on my part.thanks for the data point. my dealer did not advertise either. you give me hope!
A friend of mine helped me figure out it also had Autopilot and Hardware 2.0 and the HEPA filter. Pretty much everything except the cold weather package. I didn't think the sliding glass sunroof was a big deal but I guess Tesla stopped offering that so some people seek it out.
