Mercedes-Benz 219 Ponton
This is only the second Ponton I've ever got to see since I visited Mercedes-Benz's excellent museum at its home in Stuttgart, Germany. And the first presentable one - the previous one was a mere shell.
The Ponton ("pontoon") was a line of simple, rugged, reliable sedans for postwar West Germany and beyond, and helped rebuild Mercedes-Benz. The Ponton, the first unibody design from Mercedes-Benz, is the ancestor of all current Mercedes-Benz sedans, including the C, E, and S classes.
The 219 (chassis code W105) was an interesting model, built from 1956 to 1959. From the dashboard rearward, the car is identical to the 180/190 (W120), the original four-cylinder Ponton from 1953, complete with single-pane rear windows and the simpler instrumentation. But to the front is the longer nose of the 220, to house a bigger engine, a 2.2-liter single-carburetor 85-horsepower 6-cylinder. 27,845 were built. (Source: Wikipedia)
