To current Tesla owners. Would you share some insight on what to expect in the acquisition process? Such as: 1) Is there a garage wall charger recommended or that you prefer? 2) What kind of closing costs are involved? Tax, license, shipping, etc? 3) Insurance costs you didn't expect? 4) Vehicle registration costs you didn't expect? 5) Any costs you did not expect? 6) Anything else that you think the Model 3 buyers should know to prepare?
