When I took delivery of my MS on October 6, 2016 in Tampa, there was a $500 registration charge. I inquired about the charge and was told by email from Cameron Watson, a delivery specialist, that they are not quite sure what the charge will be, so they overstate the amount and then refund the difference in 30-60 days after the plate is issued. My plate was issued November 14, but now it is well over 60 days. The charge for registration was $345.20, but I have not received the difference from Tesla. Has anyone else had this experience?
