The Pebble Beach Concours d’Elegance is known for its traditions. Cars that participate in the 70-mile Pebble Beach Tour d’Elegance get bright green ribbons. Dawn Patrol allows attendees to get early glimpses of the painstakingly restored vehicles. The chairman greets each entrant. At the end of this year’s concours, the confetti cannons — another Pebble Beach tradition — fired their colorful ammo skyward when a 1935 Duesenberg SSJ Special Speedster was named Best of Show.

Before owner Harry Yeaggy and his Duesy took home the top prize from the 75th Pebble Beach Concours d’Elegance, the car was already famous because film star Clark Gable used to own it. According to the car guide for this year’s Concours, it’s one of only two Herb Newport-designed Special Speedsters on a shorter 125-inch chassis (the other was owned by Gary Cooper). Both cars were powered by a supercharged, dual-carb straight-eight that produced more than 320 horsepower. Yeaggy recently had his SSJ restored to the original configuration of a black lacquer exterior (which makes the steeply raked windshield and the chromed exhaust pipes stand out even more) with saddle tan leather interior.

Duesenbergs themselves are their own Pebble Beach tradition. Since 1950, they’ve been named Best of Show eight times, more than any other American manufacturer. Do the math and you’ll see that Duesenbergs make up more than 10% of the winners of Pebble Beach’s ultimate prize. And now, winning Best of Show is officially a tradition for Yeaggy, who won for the first time back in 2007. Want to guess what he brought to the event? Yep, a Duesenberg — a 1935 SJ Speedster. Nicknamed the “Mormon Meteor,” its streamlined body and supercharged engine with special cams and Stromberg carburetors enabled David Abbot “Ab” Jenkins to average 135.47 mph for 24 hours on the Bonneville Salt Flats.
