I'm looking to buy a used Tesla and have joined the forum to learn from the member's current postings. I also want to ask questions that Google searches return either no hits or ten-million hits that aren't technical enough to answer what I need. I'm guessing from the depth and breath of this forum, it'll have plenty of experts willing and able to give a more direct answer. I won't ask a question here, but my current choice is an older Model S.
