I would be willing to trade my Nissan LEAF for it so you can get that P100D off your hands and get yourself a brand new Tesla Vision Autopilot 2.0 P100D. I'll even pay shipping both ways.
But won't it be a year or more before you can use the new AP 2 features? Something about not even at AP 1 to start? Even if it's just 6 months, I'd think they'll bring updating the seats and such as well. Besides not being able to take a 30k loss and just buy a new one.
