Roth built the Mysterion in 1963 with twin Thunderbird 406 V-8s, backed by twin Ford C-6 automatic transmissions and twin 1948 Ford banjo rear axles. As the story goes, after a year on the show circuit, the car was scheduled to head back to Roth’s shop in the fall of 1964, but only bits and pieces arrived; the majority of the car, including the unique drivetrain, had gone mysteriously missing. And if you’re sure you saw it at the 2005 Detroit Autorama, that was simply Dave Shuten’s very convincing clone/replica.
Ryan’s the kind of guy who knows (and ain’t telling) the whereabouts of James Dean’s Little Bastard, so if he don’t know where the Mysterion’s hiding, then likely nobody does.
