What experiences do people here have with trading in their Model S for a new Model S? I have an "old" 2013 P85 (P05442) with 55K miles. I'm thinking of getting a new 90D so I got a quote for the trade in. They offered $42K. KBB, Edmunds, Cars.com, even AutoTrader all put the value between $52-$62K for a trade-in - up to $65K for a private sale. Do I need to talk to someone else at Tesla or are they just low baling to avoid the trade?
