 The model was an attempt to challenge luxury cars in the growing 3.5-litre class from Horch, Mercedes-Benz and Maybach.However, it came with a substantially lower price than the similarly sized and powered cars from these premium manufacturers, which combined with its generously proportioned but technically straightforward chassis to make it a favorite with builders of specialist car bodies.Unlike the slightly smaller unitary bodied Opel Kapitän introduced at the end of 1938, the Admiral used a traditional separate chassis.
