I am looking to buy a used Tesla S85 or P85, and I am trying to be mildly sensible, so I am looking for versions with some warranty left. Some of them will be close or even beyond the 50000 miles new vehicle warranty but they will all have at least 4 or 5 years of drive unit and battery warranty. So my question is: How important is the new vehicle warranty - meaning how many of the potential errors are ones that would be covered on THAT warranty? The drive unit problems is of no concern since they would be covered on the other. So which type should I be concerned about and are there many? The prices seem to drop when cars are out of warranty - so it is tempting to rely on the drive unit and battery warranty. Thanks - great forum!
