I am receiving my new P90DL on Saturday! Tesla offered my 47k for my ride - the guarantee that was negotiated with the original loan i made with Tesla in 2013. I took it to carmax on a whim this Friday and they offered me $52k No brainer what i should do. The crazy thing is that now Tesla as of this Friday will match the carmax price. I can exchange the car at a Tesla SVC and they will apply the credit to the new Tesla down payment! Highly recommend going to Carmax and getting an appraisal from them before just accepting Tesla low ball appraisal.
