The 290 Pullman was almost identical to the 230 model, having had nearly the same body styling with a rounded-box cabin featuring an extra set of rear side windows.
Other differences consist in a straight nose in comparison to the slightly slanted one on the 230 and different fender design, particularly in the rear. While typ 290 coupes had stretched rear fenders with horizontal ends, the Pullman had the same styling as the saloon with abruptly-ending arches. Of course, the Pullman came with an updated interior complete with a choice of different materials and accessories.
