Of the 25 540 K Spezial Roadsters ever produced, only three of them had a spare tire mounted on the rear, making it the most attractive of the models that were built during their 1936-1938 period. This high-speed touring car is powered by a 5.4-liter supercharged, in-line, eight-cylinder engine developing 180 horsepower coupled to an unsynchronized four-speed manual transmission. It has a top speed of 105 mph and is capable of 0-60 MPH in 16.4 seconds. The K stands for compressor which means supercharger in German.

It was the fastest production vehicle of its era and was advertised as "enormous speed combined with exeptional elegance." This particular car has traveled from it's homeland in Germany to Argentina to the U.S. to Australia then back to Germany and finally back to the U.S. The only thing more rare than the car itself is seeing the car on the public auction block.
