In typical fashion, William B. Ruger Jr. was fascinated by the engineering of the Cadillac V-16 and its potential for performance. In his ownership this original limousine, one of 54 V-16s made in the last year of production, was restored and outfitted with custom-made 17-inch wire wheels with radial tires, modified suspension for better handling, and, most prominently, custom intakes bearing dual Holley two-barrel carburetors. The original side-mounted spares were also removed from the front fenders to provide easier access to the engine compartment and more aesthetic appeal, while the front seat was moved back slightly to provide more room for the driver.

Typical of the automobiles in the Ruger Collection, all of the work was well-envisioned and professionally executed, with the aim of being able to use the car at its peak. Indeed, that Mr. Ruger loved driving the result and comparing it to the other multi-cylinder automobiles in his collection is visible in the car today. An older restoration, it shows evidence of patina and use throughout, including to the paint, while the pale green leather interior remains in good overall condition with fine woodwork trim. At the time of cataloguing, it had recorded 70,220 miles.

Very few of the Cadillac V-16s produced in the last season of production have survived, and likely none have enjoyed the mechanical attention to detail seen in this car, sorted for running on the open road by a true enthusiast. It would be a superb highway tour and automobile, with room for the entire family to enjoy sixteen-cylinder power.
