BMW->ke178 unveiled the M3 CLS (Coupe Sport Lightweight) back in 2004 when only 1,400 units have been produced. Sadly, the M3 CLS was never released in the North American market and was offered only in two exterior colors: Silver Grey Metallic and Black Sapphire Metallic.

Now, BMW is preparing to celebrate the car's 10th anniversary and it started with a very cool reunion in Munich, Germany. About 50 BMW M3 CSL owners from different parts of Europe came to this reunion and made a real spectacle of it. It’s pretty easy to get a good idea of what happened in there by watching this short video (above) released by BMW.

The M3 CSL was built using a forward-thinking intelligent lightweight technology that set the benchmark for the car construction of future models. Thanks to this construction, the M3 CLS was about 243 pounds lighter than a standard M3->ke2366. With its 360-horsepower engine the M3 CSL could sprint from 0 to 60 mph in just 4.9 seconds, while top speed was limited to 155 mph.
