Here's a couple of interesting vids with an Irish connection. They're from the street races that took place in Dun Laoghaire in the mid 1980s. You'll get a glimpse of the Irish GTs from back then including George Crozier's Maguire Metro and even Col's Imp driven by his dad, Dan. I thought I saw Maurice Mitton's space-framed Imp in there as well.
