Have a deal in place to purchase my first Tesla (17 S 90D). Also have a few weeks until it arrives...what do I need to know and/or prepare myself for? I've only ever done a test drive at a Tesla sales office, which wasn't a lot of time with the car. Also looking at doing a road trip in it to see what that's like with the supercharging and having to wait vs filling up with gas quickly. I have a 10-30 outlet at the front of my garage (pays to clean out the garage occasionally) so I think I need to order that adaptor, but wasn't sure if I needed other cables or adaptors etc.
