Hi I plan to purchase a MS CPO but I have question about about Model S CPO warranty (maintenance) 1: is the warranty same as a new car warranty (I heard there is a copay of 200 for extended warranty). is it free for a cpo warranty? 2: The new car warranty includes free yearly maintenance, how about the CPO? Do I have to pay for yearly maintenance or is it free? 3: If I forgot to do a yearly maintenance, is that going to void my CPO warranty? (4year 50k mliles) thank you in advance for answering my question.
