Technically no. No Florida Nissan dealer will not commit to a price. All Nissan dealers around me are adding $5K to $10K markup. I have one that agreed to $2.5K over MSRP via text/email but they said the MSRP isn't official yet so they can't give me a price sheet. I moved my order from my original Orlando area dealer who said between "$5K to $10K" markup on MY reservation to this $2.5K markup dealer because it's the best I've found and they have the best reviews.
In Canada, at least you pay MSRP.
I have nothing to support this, but I suspect that the real reason Nissan shut down the reservation process in the USA was because of the unstable and rapid rise of EV production costs in the past 6 -8 months.
(If my suspicion is reality, this scenario could also be why Canada hasn’t seen published MSRP because the timing of their launch began around the time when EV mfg. costs really began to spiral out of control .)
As Ariya USA reservation holders who have agreed to a published MSRP, we can only hope that Nissan will follow through with their original commitment. Personally I’m hoping that Nissan was paying attention to the negative press and outcry of long time Rivian reservation holders once they were told that Rivian could no longer hold the line on MSRP. If you hadn't been following that story, Rivian eventually did succumb to the pressure and agreed to walk back their price increase to previously ordered customers.
Soaring EV costs are pretty telling as we see that the Cadillac Lyric and Ford E-150/Mach -E reservations have just reopened with substantial price increases.
