Four words: "Rear door Intelligent Access".Let's not forget that the 2019's also get LED puddle lights from the factory and a rear defuser. Calling the 2019 "DE contented" is just not true and that term needs to stop being used.
I'm sorry, but that's decontenting. It is what it is. Like I've said before, the different years have WAY more in common than they have differences, and again, it's a personal choice. The LED puddle lamps are a nice feature of 19s! But I can add those to an 18 without it being too much of a problem. I've not seen anyone add rear-door Intelligent Access to a 2019 though. I imagine that would be a fair amount of work. Honestly, you could technically add anything, from any year, to any of these cars, because the platform is the same. So if you're willing to do the work you can do it. But my point is that, for me, the 18 made the most sense. I understand the appeal of all of the different years. It just depends on what a given person wants. They're mostly the same anyhow. But let's be real, when Ford is removing features that IS decontenting. I don't like it, but I understand why they do it. It is what it is, though.
