This 1972 BMW 3.0CS was purchased new by Dahmen-Tuning in Germany and subsequently converted to racing specifications. The car was campaigned professionally by Heinz-Jorgen Dahmen for years and eventually imported to the US. It was then acquired by Cullen “Cuffy” Crabbe and converted to Group 2 specifications, including the installation of a race-prepared S38 3.5-liter inline-six and 5-speed manual transmission from an E28 M5 or E24 M6. Cuffy drove the car in numerous vintage races until it was acquired by Adam Carolla in 2011 after he saw it compete at Coronado. Carolla has not raced the car, and it has been maintained as part of his private collection since. This E9 racer is now being offered in Glendale, California on a bill of sale with Heinz-Jorgen Dahmen’s original Wagenpass, recent service records, an extra set of wheels, and a collection of vintage photos.

Adam Carolla gives an overview of the car in the video above.

According to the seller, Jim Simpson at Simpson Motorsport in Iowa performed the Group 2 body conversion after the car was imported to the US. The seller has provided 30+ detailed exterior pictures in the extensive gallery below.

In 2011, Carolla had the above set of gold-centered multi-piece BBS wheels custom made. They are currently equipped with Goodyear Eagle slicks, and each corner is highlighted in the gallery. An extra set of competition wheels is also included with the sale.

The cockpit features a Sparco Pro2000 racing seat paired with an unused Sparco harness that expired at the end of 2017. The full roll cage includes door bars as depicted above.

Other equipment consists of custom auxiliary instrumentation in the center dash, a thick leather-wrapped steering wheel, switchgear mounted forward of the shifter, a brake bias lever, and more. A fire suppression system is also fitted but will need to be re-certified before any official competition use according to the seller.

In stock form, the 3.5-liter S38 inline-six produced 255 horsepower and 243 lb-ft of torque. The engine in this 3.0CS has been fitted with free-flowing headers, triple Webers, a custom intake system fabricated by Adam Carolla himself, side-exit exhaust, an MSD electronic ignition system, and much more. Since acquiring the car in 2011, new custom-made silicone hoses were installed, the carburetors were rebuilt, the spark plugs and fuel lines were replaced, the engine wiring was cleaned up, and an oil change with Driven Racing Oil was completed.

Additional undercarriage pictures are displayed in the gallery below.

Several recent service records and a host of older photographs accompany the sale.

The original German Wagenpass is also included. Each page is detailed in the gallery below.
