Yes JW, the late 1960 was a great era for motor sport across the globe, particularly rallying given the enthralling 1968 London to Sydney Marathon. What I also find interesting about the makes and models you've highlighted competing in the 1968 European Rally Championship is that there's not one Japanese or Korean brand listed. That's indicative of how much the global car industry has changed since then given Toyota and Hyundai (below) are heavily committed to the World Rally Championship and many regional championships.
