My guess is that you are getting a MY12. The ordering dashboard should show that at the bottom center (under the car's picture).
At home, you can install any EVSE you'd like. Skip the AV assessment and use the $100 fee towards your install cost. After great deliberation, we went with the unit from Schneider Electric. Total cost including install* was USD $1,650 (80% of which is covered by rebates**). The lowest cost unit is possibly made by Ingineer who is active on these forums. Hope that helps..
* this varies based on the wiring setup in your garage.
