Sounds like you went in to the dealership looking for issues. I have seen this multiple times in experiences at other dealerships. However, you're entitled to getting these elements fixed and it sounds like Tesla offered to rectify your concerns much to your dismay. Being an inventory car with that many miles on it, you probably go a sizeable discount. My Model S was the best investment I ever made and I have never had a bad experience, much like the vast majority of owners I've met. You got the car 3 months ahead of a custom order and for a sizeable discount and access to a credit that could deplete at any moment. Overall, I think your experience was slightly below average, but your reaction or preconceived ideals contributed to making the situation worse, IMHO.
