At the time, the '86 Olympus was very important because it was to decide the championship between Alen and Kankkunen. It's the only reason those two even showed up. But in the end, FISA decided the championship in a boardroom later on.
I have a highlight show of the '86 Olympus on VHS. I also have seen footage from the '87 Olympus in a season review. Alen is extremely pissed because during the first stage, he encounters a civilian driving a Mustang along the road. There is almost a big accident.
