If anyone is trading a Tesla or other vehicle when buying a new Tesla and you are not satisfied with what appears to be a low-ball offer from Tesla, I suggest consider using a third party buyer like Carvana, We Buy Any Car, Car Max, etc. You may get a better offer that is worth the effort even after taking into consideration the sales tax offset for the trade-in (if allowable in your state). After receiving a low-ball offer from Tesla for my 2018 M3 AWD, I accepted the offer from Carvana which was SUBSTANTIALLY higher than the Tesla offer. Smooth transaction online. And I got paid within 24 hours with direct deposit after my Tesla was picked up at my home.
