I wanted to start a new post but let me comment here. I own two Tesla Model S cars. When the Model 3's roll out I truly believe that Tesla is in over their head when it comes to being able to service their vehicles. Appointment wait times are beginning to increase to a point where buyers of luxury vehicles will not tolerate. Example: I need to swap out my all season 19" wheel/tires for my summer 21" wheel/tires. Basically put car on lift, take off 19's, and put on the 21's. The next available appointment for this 10 minute job is 3 WEEKS ! Are you kidding me! What will happen when all the Model 3's hit the road ??? This may be Tesla's biggest problem down the road. BTW I took my car to local service station and they did the wheel switch while I waited same day.
