I reckon that Silvercloud and Moparlover have provided the main reasons for KF's demise. Back in 2021 I did a Retroautos story that celebrated memorable cars of 1951, one being the Henry J. Part of that story also included some reasons why KF failed. Here a link: https://www.shannons.com.au/club/news/retroautos/milestone-cars-of-1951-70th-anniversaries/ And I too recommend the Langworth stories in Collectible Automobile. BTW, BentleyT, that photo looks like AI has been applied to re-imagine a KF sedan into a coupe hardtop, because such a car was never built. The four door sedans were not very attractive, which is another reason they failed. They AI coupe looks ok.
