Hitler also owned a Mercedes G4 offroad model, he also gave one to Spain's Franco as a gift. Only 54 of these were produced, for pics of Franco's G4 see:
No-expense-spared restoration of a rare G4 1939 Mercedes Benz
The car is now owned by the the Spanish royal family, and it still wears the factory paint, and interior. Franco used this car primarily for hunting game, and would rest his shotgun on the drivers shoulder. Most of Franco's close henchmen were provided with Adenuaer models during the '50s, though Franco was driven mostly RR Silver Dawns.
