The Cadillac “V-12” is an exclusive overhead valve V-12 powered luxury car, manufactured from 1930 to 1937. Below only the maker's top-of-the-line V-16, it was built in relatively small numbers. It was Cadillac's first, and is to date, Cadillac's only standard production V-12 automobile. The 1931 V-12 (Model 370A) was introduced in October 1930 and a roadster was used as the pace car at the Indianapolis 500. It had a shorter wheelbase than the V-16 but offered a similar choice of Fisher and Fleetwood semi-custom bodies. It was difficult to tell a Cadillac V-12 from a Cadillac V-16 and, significantly, thanks to its lower price, the V-12 outsold it. The amazing 1931 convertible auctioned was bodied by Fleetwood. Of US origin, it was purchased in 2005 by the current owner who registered it in the Principality of Monaco. Extensive documentation of the complete professional restoration (dating back ten years) and important technical documentation testify to the care that the car has been subjected to. The car, painted in a delightful two-tone ivory/black, is in perfect condition, the soft top is new. Hundreds of details underline the luxury, such as in the passenger compartment where briar wood and embossed and polished aluminum are combined with sumptuous black Connolly leather. Among the accessories, an interesting and rare set of Berg suitcases. Also peculiar is the safety lock on the wire wheel hubs, equipped with white-wall Firestone tires and, finally, the magical deco statuette that adorns the radiator.
