I don't have my car yet, but in anticipation of getting an inventory car shod with summer 21s arriving in october/november in Canada I started arranging winter tires before delivery. As part of that my DS arranged for me to purchase TMPS sensors from the Vancouver service centre. When they arrived the FedEx parcel also contained 2 Tesla Driver's Group hats in a Tesla lunch bag.
I don't expect anything else with the car, but of course I won't turn down a pleasant surprise!
(I especially don't expect anything because we don't yet have a Tesla service centre, or store in Calgary, so the car is going to get dropped off at my house, not much opportunity to "shop" for swag that way!)
