The best used Model S to buy is a 2017 or newer because those come with side cameras in the fender for full self-driving capability. A major issue for older Model S cars is screen delamination on the dash screen or 17-inch vertical screen. The MCU2 upgrade for around $1,750 replaces both screens. Also, the tires of Model S cars tend to wear on the inner tread, requiring an alignment. This smart air suspension lowers the car at high speeds, causing extra inner tread wear. Tesla vehicles can be "uncorked," increasing power and acceleration. A polite request to Tesla service centers may lead to this performance upgrade.
