The good citizens of the United States have spoken. Behold - a preview of the ‘28 Quartermaster design.I wouldn't be surprised if the changeover happened during the shutdown.
Factory 23.5 with that date.
However, the reverse camera is the main way to tell if you have the only "real" difference between the 23/23.5 and 24.
I don't see Ineos doing major changes over the years, but instead, just tweak a bit here and there based on third party manufacturer updates. Maybe add more things that they said they wouldn't put on the car when the project started! Possibly things that US buyers or reviews on YouTube moan about not being present. With the US being the major market, I reckon US desires will drive the things they add.
