so i am expecting Model 3 delivery next Fri 6/28 - yay! i'm still kind of gobsmacked by this whole thing of getting a car delivered to my house. i'm curious, approx how long did it take to go thru the checklist and inspect everything was working ok before accepting? just want to be prepared for being outside for a considerable amount of time (yep, i'm still not use to texas heat). i don't have any shade at all. and for trade-in, do they literally just drive the other car off after inspecting it?
