I leased without autopilot (given that it's unclear the full feature-set will be available within my 3 yr lease). I wonder if it's possible to add AP to an existing lease given that it's a $3000 added charge. It's a strange thing to consider because it's a software-only change, done OTA, but does (presumably) increase the value of the car by some amount. Does AP depreciate along with the car's hardware? Or does it hold its value (or even appreciate!) over time? And the big question: can US Bank even handle a mid-lease change like this?
