Collector Grade Example, Restored by Oldenzaal Classics

The 1973 BMW 3.0CSi is more than just a classic; it's a pivotal chapter in the story of the "Ultimate Driving Machine."

The 3.0CSi belonged to the legendary E9 coupe family, which succeeded the rather quirky-nosed New Class coupes. Launched in the early 1970s, the E9—with its elegant, pillarless coupe design, long hood, and signature "shark nose"—was an instant design icon. The coachwork was famously handled by Karmann, lending the car a distinct, handcrafted touch.

The "i" in CSi is where the magic really happened. Following the carbureted 3.0 CS, the 1973 3.0CSi brought cutting-edge Bosch D-Jetronic electronic fuel injection. This was a big deal for the time, replacing fiddly carburetors for smoother, more efficient power. This mechanical upgrade boosted the venerable 3.0-liter straight-six engine (the glorious M30) to a hearty 200 horsepower. The CSi was the spirited, top-tier road car, able to sprint to 60 mph in a brisk 7 to 8 seconds and hit a top speed over 130 mph. It solidified BMW's reputation for building performance luxury cars that could dance.

Beyond the engine bay, the 3.0CSi was a proper Grand Tourer, combining sporting dynamics with old-world luxury. Drivers enjoyed the intimate connection to the road through a standard four-speed manual transmission (a three-speed automatic was available on the CS, but the CSi often came with the manual) and a sumptuous, wood-trimmed cabin. While a beautiful car in its own right, the CSi also served as the essential platform for the legendary, lightweight 3.0 CSL "Batmobile" racer, which dominated the European Touring Car Championship.

In short, the 1973 3.0CSi stands as a masterpiece of design and engineering—a charismatic and fast coupe that paved the way for the high-performance BMWs we know and love today. It's a gentleman's express with a racer's soul.

The 1973 BMW 3.0CSi offered here is a rare Euro-market jewel, born on March 16, 1973. Finished in its factory-correct Fjord Metallic (37) paint, this elegant E9 coupe underwent a comprehensive revitalization between 2018 and 2019, including a full repaint to restore its iconic luster.

Beneath the long hood lies the heart of this Grand Tourer: the classic 3.0-liter M30 inline-six. Equipped with Bosch D-Jetronic fuel injection, the engine was reportedly rebuilt prior to its importation. Power is channeled to the rear wheels via a proper four-speed manual transmission, ensuring a direct and engaging driving experience.

Recent maintenance in October 2023 ensured this classic is road-ready and reliable. Work included a valve adjustment, a cooling system flush with replacement radiator hoses and fan assembly, and renewal of the front cover gaskets, valve cover gasket, distributor, and spark plugs. Furthermore, the differential was resealed, and a new clutch slave cylinder was installed.

The coupe sits aggressively on staggered-width 16″ light alloy Maxilite Alpina-style wheels, wrapped in Achilles ATR Sport tires (205/55 front, 225/50 rear). Performance handling is enhanced by H&R lowering springs. Stopping power comes from discs at all four corners. In 2023, the brake calipers were re-plated and the system was flushed. A set of stock 15″ light alloy wheels is included, along with the BMW Classic Certificate and a collection of recent service records.

The sophisticated cabin is upholstered in rich blue leather, covering the front bucket seats, which feature headrests and modern three-point seatbelts, and the contoured rear seats. Interior amenities, perfect for comfortable touring, include power-operated windows, a heated rear window, a heater, and a cassette stereo. The driver grips a sporty Nardi Torino three-spoke steering wheel, which frames a 240-km/h speedometer and an odometer displaying 8k kilometers (though total mileage is unknown). The removed stock steering wheel is also included in the sale.
