It seems that Tesla's Gigafactory battery metropolis had a fancy new visitor recently and the pics above and below were snapped by various workers and visitors as proof. Above we see a 3/4 rear shot of the Tesla Model 3 which shows its sexy back half and wrap over glass roof. Below we have a front shot clearly showing the front fascia and the control panel that is visible next to the steering wheel.

Here's a closeup shot of the center mounted display. When the car was first shown the display was on a swivel mount that seemed like a temporary position, while this seems to be a more permanent mounting. The full Model 3 dashboard and interior of course is still yet to be seen at the official 'Part 3' of the Model 3 introduction which will take place in the coming months. There's more shots at the source below.
