I received my Model 3 SR+ on Wednesday (Aug 7th). That morning, I received an e-mail from my DA saying the car will be delivered on Thursday (8th) and I would get a phone call before delivery to make sure I was there. I didn't get a phone call and it was a day early. I found it sitting on my driveway when I arrived home from work. A pleasant shock, but a little unexpected. I couldn't get into the car, but a phone call to the Tesla call center fixed that problem, and the key cards were put in the front trunk.
The car looked fine, a bit dirty from rain, but otherwise a beautiful ride.
