I had a online chat with Nissan today and I am happy to tell you what they said.
Patrick:
Thank you for contacting Nissan EV Customer Support. My name is Patrick. How Can I help you today, Jim?
jim:
Hi I have been selected for the DOE EV project and I have will be ordering the SL model. Will the L3 port be an option I will pay for or is it included free because I am in the EV project?
Patrick:
Since you are a part of the EV project, the level 3 quick charging port will be placed on your car at no cost to you.
jim:
When I order the car and receive a quote. If I do not like the dealer price can I reject it and ask a different dealer for a price?
jim:
thank you for the first answer
Patrick:
The Price is negotiable between you and the dealer. If you do no like his price you are free to chose another dealer.
jim:
Do you know what value the quick port is?
Patrick:
Not off hand Jim.
Patrick:
If you would like to wait a moment i will see if i can locate that information for you.
jim:
ok
Patrick:
Jim, I do not have the cost of the level 3 charging port available.
Sounds good something I was wondering about.
