I was in Atlanta in 1983, working on the movie Tank at the old Lakewood Fairgrounds & Audi was having an event there & somehow got to ride around the old Lakewood Park Speedway, with a salesman? I'd say the car must've been a Quattro(IIRC)as it was a dirt track. And his driving didn't impress me with the concrete walls, and the tracks' reputation. And track not prepared. Rough & rutty.
