I just got back from picking up a P85d (not mine), and did a factory tour. Wow! This was such an amazing experience. From the tech to the plant itself, it was really impressive. Especially considering how short a time Tesla has had to convert it to their needs. Its amazing to start the tour holding some solid aluminum and some rolled aluminum sheet examples, to then seeing the process of all the parts being molded and assembled into a car in the end! Very, very cool. It was like a high tech sci-fi movie with all the robots. Anyone who has the chance should do it!
