The Appeal

The BMW 3.0 CS is one of the most elegant grand tourers of the 1970s, a Karmann-built coupé that married BMW's refined six-cylinder engine with a body design that has aged remarkably gracefully. Among E9 enthusiasts, the 3.0 CS holds a particular appeal as the civilised, carburettor-fed touring coupé, and good examples are increasingly difficult to find.

The car’s allure lies largely in its pillarless profile, which creates an airy, panoramic cabin and a silhouette that feels surprisingly modern despite its vintage. Inside, the driver is greeted by an interior defined by high-quality wood veneers, plush upholstery, and a driver-centric dashboard that established the ergonomic blueprint for BMWs for decades to come.

Beyond its aesthetics, the 3.0 CS is defined by the buttery smooth power delivery of the M30 inline-six engine. While its fuel-injected sibling, the CSi, and the homologation-special CSL often grab the headlines, the carburetted CS offers a more visceral, mechanical connection that purists adore. Driving one today is less about outright speed and more about the effortless torque and the melodic straight-six hum, making it an ideal companion for long-distance rallies or leisurely weekend cruises through the countryside.

This 1973 example has been registered in Germany throughout its life. Between 2021 and 2023, it underwent a thorough ground-up restoration carried out by Auto Kout Centrum in Prague. The body was fully stripped, treated, and repaired with Walloth & Nesch panels to key structural areas before being refinished in its original BMW colour. Mechanically, the engine, carburettors, transmission, braking system, and suspension were all addressed as part of the restoration, with full details outlined below. The car holds a TÜV condition score of 1.5 and is registered on German historic plates, ready for its next custodian to enjoy.

Powered by the robust 3.0-litre M30 inline-six producing 180hp, paired with a smooth three-speed automatic transmission, this BMW delivers effortless performance. The engine has been thoroughly refreshed with a full gasket replacement, while the twin carburettors have been expertly rebuilt and tuned.

Significant mechanical attention includes new copper KUNIFER brake lines and repairs to key components such as the heat exchanger, with ancillary items like the radiator and brake master cylinder cosmetically restored. Minor electrical points remain, with the radio currently inoperative and door speakers requiring reconnection, but these are small details in an otherwise well-sorted and highly usable classic.
