He already had won three titles and wasn't interested in participating in the full grind anymore. Wanted to run all the big races and have time to spend with his family. This Cyclone won 11 of 18 races entered rivaling only Glenn Roberts 1958 season - six wins from 10 entries in a '57 Chev - for highest winning percentage for one car in a single season.
Great addition to any collection and one I added earlier this year for a bargain price of Cdn$150. Unautographed, the way I prefer them.
