I've just discovered these gems from 1967 illustrating the differences and advances made for all the 1968 models. All of these changes were occurring in the space of just one or two years and it still amazes me that only in the US could they have had so many constant evolving themes in such a short time. Love the bit about being greeted with a tangle of seat belts, but many of these illustrations were about safety in those just post-Nader days.
