Tesla Model S Buyers', Delivery and Owners' Guide (get to the bit that says "The Big Day" and start there)
i've built a checklist out of that to keep on my phone - a whole list of items that i went thru one by one as i received the car. dont worry about taking your time, it's a 20-25min job even when you go thru your new car with a fine tooth comb. it'd be a lot more time needed trying to book the car back in to get something minor fixed afterwards!
also, check if they're already included any sort of charging cables/ other accessories with the car (those would've been mentioned at the time of ordering the car) so it saves you a trip back later on.
