for the bread and butter vehicles I would agree, the 4 door sedans, basic CUVs and SUVs. But for either work based vehicles and enthusiast vehicles that's not the case. That would the f-series, broncos, mustangs, corvettes, etc.Though I totally agree with this vision from a system engineering perspective, from what I have seen I am not convinced that PD engineering considers much past efficient delivery, low warranty and high initial value to the customer. And Ironically we fail at those more than we should...
I'll edit to add:
It's not necessarily the vehicles that keep the bills paid that the manufacturer cares about the 2nd or 3rd owner, it's the vehicles that get people to stop in and look, even if they buy that Escape instead of the Bronco Sport, or they buy that fusion instead of the Mustang because they have 2 kids.
It's the vehicle that Ford uses to say : 30million F-150s are still on the road or whatever number they use these days.
It's the vehicle that The company stakes their reputation on, that they care that the second owner or third owner still have a solid experience with it, because seeing that 20 year old mustang still on the road may help get someone else into look at them. (I see 10x more 90s Mustangs on the road than camaros, and while I used to see plenty of F-bodies in comparison to Fox bodies, that is no longer the case. I can't recall the last F-body camaro I've seen, but have see a couple of foxes in the last week (talking about the 80s era iroc style camaro).
