Oh, here's my new Model 3 on the day I got it. Named it Rudolph (the reindeer, not the corrupt politician)
It's fast. Like ridiculously fast. I don't know that I've ever been in a car so fast, let alone drive one. Launching feels like you are shot out of a cannon, or like a roller coaster that starts from a dead stop (Flight of Fear or Volcano, for the old school Kings Dominion heads).
Auto pilot and Auto steer are two things that actually caught me by surprise. I never use cruise control. These two features make driving on highways a breeze. Just set it, and the car does the rest. Goes as fast as you want, follows the cars in front of you as far away as you want. Slows down and speeds up with traffic. Changes lanes when you put on your turn signal. Keeps the lanes very, very well. I was amazed.
I have no info about the Model X. Couldn't even tell you what their base price is. Bears noting that at least on the Model 3, the base model leaves enough to be desired that you'll naturally gravitate towards the more expensive models.
I can say that I'm not a huge fan of the wing doors though. Seems like they might get in the way, such as in a garage where side space is limited.
