Elon has been on a Twitter rampage answering all kinds of questions about Model 3. Today we heard it will have a towing hitch option. Just now he said the AWD option will cost less than the $5K cost of it for Model S. https://twitter.com/elonmusk/status/716747844175142912 Seems to be an indication that Tesla wants to keep Model 3 options costs in check and keep them reasonable in order to increase the take rate. I think it's a good plan. I'll add more links as he responds.
