Chryslers of the late 1920s and 1930s were not only very strong and robust touring cars, they were actually quite fast for their day. Between 1925 and 1931, Chryslers competed internationally at events such as the Mille Miglia, the Le Mans 24 Hours, and the Spa 24 Hours racking up impressive results amidst world-class competition that included Bugatti, Mercedes, and Alfa Romeo.

This 1931 Chrysler CM-6 was prepared by Martin Swig in the style of the sporting competition cars of the period. Martin had previously raced a 1931 Chrysler CD-8 at the Mille Miglia and at the Monterey Historics at Laguna Seca, where he took great pleasure in regularly beating Blower Bentleys. He intended to pursue a similar project when the opportunity to acquire this very good CM-6 presented itself in 2002.

The car had been in the longterm ownership of Charles Giese in Billings, Montana, who had owned it since at least 1964 according to an old Montana title. It passed briefly to Mark Hyman and then to Swig, who immediately transported the car to Pit Stop Automotive in Brisbane, California, for its rebirth as a dual purpose competition/touring car.

Swig added triple Zenith updraft carburetors on a custom manifold, along with forged pistons and a higher 9:1 compression ratio. The look was completed with the windshield folded flat and a pair of Brooklands competition windscreens adding a touch of aggression; a Jaeger tachometer was added for the driver.

The Chrysler retains its ability to act as a capable car for lower speed touring and parades, and remains eminently usable on the road. It truly exemplifies its dual personality on the track, however, where without much fuss or bother, it has been known to run with--and occasionally beat--supercharged 6C 1750 Alfas, Bugattis, and more than a few purpose-built pre-war racing specials. It ran successfully in the Monterey Historics on several occasions, including an excellent drive by François Castaing in 2004.

We are advised that this excellent touring car would be a welcome entry for the California Mille. It certainly offers its new owner a substantive pre-war motorcar, with sporting ability that belies its more genteel looks!

Offered on a California Certificate of Title. This vehicle is titled by its engine number.
