I have a buddy who was contacted by Tesla to trade in his current S85 for a 90D with AP. He got a great deal on trade-in. Essentially was paying the same monthly payment for brand new car with all the upgrades. This occurred in late Nov of 2015 and his understanding from Tesla was that Tesla gave more than usual for the trade-in as they were trying to hit their new car sales numbers by the end of the year. I inquired in early December about the same deal and was quoted a terrible number for my trade-in. I guess the December trade-in was too late for them to be able to book my sale by the end of the year. Anybody else seen this? Is it a quarterly phenomenon or just end of the year?
