I am selling my S85, and the car has the Extended Service Agreement. The Agreement says that I have to notify Tesla, pay a $100 transfer fee, etc., but the document says nothing about who to notify, how to pay, etc. I have emailed Tesla Scottsdale Service, but am still waiting for a reply. Does anyone know exactly how the ESA transfer is actually done? Comments from owners who have actually transferred the ESA would be much appreciated.
