I ordered my Model S back in September. Prior to placing my order, I got an estimate on a trade in for my current (11 year old) car. It seemed reasonable, so I placed my order. Now that I am 10 days away from delivery, they gave me a new, firm offer - which was 33% lower than the original. While I understand there is some minor cosmetic issues (all fixable with a good detail), there are NO mechanical issues at all. I am very frustrated that the offer was so much below the original valuation I received from Tesla. I was upfront with them and told them about the car. Any car that is 11 years old will have minor dings in it. My DS is telling me he can't do anything about it. This is very frustrating, and is negatively impacting my impression on how they are supporting me. Once I committed to the purchase, they no longer seem to care.
