For those who have done the MCU2 upgrade, I have an appointment to do the MCU2 upgrade on 2014 Model S85. Does the $1750 include labor or not? Seems like the wording, "This upgrade is available for $2,250 plus applicable tax, including installation, for vehicles equipped with Autopilot Computer 2.0 or 2.5 and for $1,750 plus applicable tax, including installation, for all other vehicles." can be read either way. Thank you.
