I am looking for a late model S as my first Tesla. Budget is around 65k. i found a 2017 with 34k miles, it has a 90D battery. (Loaded with extras, dealer wants $65k) As I read through the forums it looks like there are issues with this size battery? Any chance of a software fix? Should this model be avoided? What else would you suggest I consider? Want AP2.0. Also can I transfer nay remaining warranty or supercharging if I buy from a 3rd party? thanks!
