Hi Jeff,
I feel sure the later models can be converted, but I haven't seen any yet.
To be honest, I have not seen a late models on the road yet either. (But I live in "Sleepy Devon").
My opinion on this, and it is an opinion, is that there a so few post 2015 vehicles about (at the moment) that there is is no commercial market yet for the conversions.
So no one is doing them.
I suggest you phone the better convertors and ask them !
Which ones come to mind?
There is a list on this Forum (somewhere).
I can also anticipate that swivel seats in the middle row will be a problem on later models; until, that is, some enterprising company .....
I do not have a view on the Nissans.
All newer vehicles are becoming ever more complex. Tapping into their systems could prove tricky for the unwary.
