The 370S was one of the first automobiles built following the merger of Daimler and Benz in 1928. Interestingly, it's a Benz design engineered by Ferdinand Porsche and is one of only three Mercedes designs to feature a flat radiator (as opposed to the V-shaped radiator that remains the standard today).
This Mannheim is one of only 183 that were built and is one of only 12 to still be in existence.
This magnificent vehicle is housed at the Kemp Auto Museum in Chesterfield, Missouri(near St Louis)and was the official poster art for the Concours as painted by the renowned artist Jay Koka
