We didn't see too many of those in the US. In fact, the first Mini (or Morris) I recall seeing was in Nova Scotia. Later they showed up in club racing at Lime Rock. I crewed for a Super Seven but I never got to drive it. The owner was smarter than that.
When I was in high school a friend's father drove a Humber Super Snipe. Where he got his hands on that I have no idea. It wasn't even one of the
50's models that looked sort of classy. It looked more like an aborted Studebaker.
