According to RM Auctions, Capone purchased the car new and quickly had it armored at a local body shop. Now 93-years old, the son of the body shop's then-owner clearly remembers his father installing steel plates to the rear of the Cadillac and Capone personally showing up to pay for the job and pick up the car.
As its name implies, the Cadillac is powered by a 5.5-liter V8 engine that sends 90 horsepower to the rear wheels via a three-speed manual transmission. Mechanical drum brakes all around take care of stopping the car.
Apart from its proven connection with Chicago's organized crime, the Cadillac holds a special place in automotive history as one of the oldest surviving armored vehicles.
RM Auctions estimates that the Capone-owned Cadillac will fetch anywhere between $300,000 and $500,000. Stay tuned to Leftlane for a post-auction update.
