This is just my personal experience, but when I picked my car up I had to go inside the ghost town of an office at Marina Del Rey and speak with the only employee there. Before I could even see the car I had to accept delivery online at the desk. My payment was made via ACH several days earlier so I can’t speak to handing over a cashiers check, but presumably they’d have wanted it before I could accept delivery.
Then the one employee at the desk helped me pair the car to my Tesla app and sent me on my way. Fobs and card keys were in the car in the parking lot (and weren’t paired to the car by the way, had to take it to a service center to get there done).
I suppose I could have asked to inspect the car, but I didn’t. Once I got it, everything was fine (excellent actually other than the fobs and card keys not being activated), so I can’t speak to how any issues were resolved.
