I have wanted to buy the Tesla S since I saw it 3 years ago. Can I get a few answers ? do all S have rear facing jump seats. are leather seats standard? panoramic roof ,sun roof ? How many different are there? the dash ( in front of the wheel ) on ever use S I look at looks different. Why is that? I have a 240 volt arc welding plug in my garage, will this work to charge the car? How long will it take?
