Opel Diplomat 5.4 V8 Automatic
The Opel Diplomat is a luxury car manufactured by Opel from 1964 to 1977. Opel's top-ranging models were traditionally the Admiral and Kapitän, introduced in 1938 and 1937 respectively.
In 1964, these models were joined, in the so-called "KAD" (Kapitän, Admiral, Diplomat) range, by the new Opel Diplomat. In most respects the three were badge-engineered versions of the same vehicle.
