I'm looking to buy a used Tesla in the next few months, I've gone on a few tests drive and love the S 85. As I've never owned a Tesla I figured what better place to get advice. I have heard from some people do not buy a used Tesla without the extended warranty. Other's have told me not to worry about it, and of course the sales reps just string you along. I have heard a lot of mixed messages on buying a used Tesla, any advice you all have would great . Thanks!
