I bought a 2016 Model S direct from Tesla a few months ago so thought I'd share my more positive experience.
Enquired via website once or twice with no reply, however when they did get in touch and I had a contact (Pieter who was very helpful) then it was quick to get specs and images of cars.
Lots of cars seemed in poor condition with images of scratches, leather scuffs etc however I went with what I saw as a good deal and was pleasantly surprised as the suffs and scratches were MUCH less visible than on the very critical photos.
I found them actually very helpful having put down a deposit and changing my mind and they moved it to another car to complete.
It did then take a bit of chasing to locate the car etc however that sounds a bit par for the cause.
Buying direct has the big benefit of the 2/4 year extended warranty which I wanted for peace of mind.
Previous screenshot look like tesla-info data so not tesla specs.
Overall very happy with the car, so good luck to people waiting!
