1. it's not personal, it's business. there's absolutely nothing wrong with due diligence, nor reason why your tesla rep would have to take things personally.
2. my local service centers and its staff have been courteous from delivery to post-delivery visits. i still trust them to do their job, which does not preclude me from bringing up items that require servicing.
one of the cosmetics i had was a scratch along the edge of the door. it looks 100% like the effect of the car "dooring" a wall. i took delivery in the midst of a blizzard, then came personal scheduling stuff, then came corona........ months later i returned to have the scratch addressed, and because it was documented at time of delivery, they instantly accepted.
if YOU were the kindest nicest car dealership in the world, and a customer returns half a year later and claim "theres a scratch/dent/ding on my car, it was this way from the factory", would you believe the claim?
