Let's put it this way - my car was built in September 2022, and I took delivery in December 2022. I was told it was MY 23. MY23 was the first year they added canbus encryption; I assume mine has it because when some scrotes tried to steal mine, they unclipped the front wing, and disconnected the headlamp, but didn't manage to steal it. It also has the revised multimedia as fitted to the NX, which I believe was a change for MY23.
I did also spend all my working life working for car importers and manufacturers!
