Ok since I've found my way back here after a long, long time away and I'm now back to expert level I'm going to try and sort out my abandoned puzzles. GTC218 is Calder Park shown during the 1980 Australian Grand Prix. Cars include Alfredo Constanzo in car 84 (Lola T430), John Bowe in car 11 (Elfin MR8) and Garrie Cooper in car 12 (Elfin MR9). Going back through the post it looks like faksta got there first and gets the point. Let me know if I've gotten that wrong...
