I am planning to place an order for a Model X, any day now, and expect it to arrive in next few weeks. Last week I visited this thread for the first time and realized few Model X on sale here only had few hundred miles and I was curious why would someone sell it so soon after owning it. I can understand some of the sellers maybe wanting to get an Auto Pilot version 2 and maybe getting ride of pre October 2016 Model Xs but are there any other reasons for them to put it up for sale so soon? Just wanted to make sure I have done my homework before I place the order. Thanks in advance for the response. Best!
