American Rally Champion John Buffum was there in his ex-Pikes Peak, Michelle Mouton Sport Quattro, backed by Audi of America. The factory Audi team withdrew from the WRC earlier in the year after spectators were killed on the Portuguese round. Too bad, it would have been cool to see the S1 E2 winged wonders from Ingolstadt.
New Zealander expat Rod Millen coudn't run his regular American Pro Rally car, a 4wd RX-7 due to FIA rules, so he ran a Mazda 323GTX in Group A. He was to win the class.
Toyota was the roundabout sponsor of the Olympus Rally, sending a 3 car works team of Group B Celica Turbo's to the event. Two cars for their regular factory drivers of Bjorn Waldegaard and Lars-Erik Torph and a third car car for Steve Millen. The works drivers finished the event but Steve was to crash out.
At the end of 4 days and 525 km of competitive driving on gravel, Markku Alen won the event by 3 and a half minutes over Kankkunen and clinched the driver's title. John Buffum finished 3rd, 24 minutes down on the winner. His third place was the highest placing of an American on a WRC event and still is today.
Above I mentioned the tradgedy of the 1986 season of driver and spectator deaths. The controversy was in the Italian round of the WRC at San Remo, where the Italian organizers disqualified the Peugeots from the event, leading to a Lancia win and was key to Markku Alen's points total necessary to win the driver crown. Seven days after the event, the FIA overturned the San Remo results and the loss of points stripped Markku of his title and gave it to Juha Kankunnen. Ironically, they would be teammates at Lancia in 1987 at the dawn of the Group A era of the WRC.
